Anyone?

OpenStudy (anonymous):

1)10,5 Strawberries

OpenStudy (anonymous):

2)10,7

OpenStudy (anonymous):

thank you so much ;)

@Mesopretty Hello??

OpenStudy (anonymous):

@Mesopretty Don't leave like this I need help please

OpenStudy (anonymous):

I can help

OpenStudy (anonymous):

a) the slope-intercept form is y=mx+b. choose 2 points from the strawberry line. choose (0,0) and (2,4). To find your slope, or m, do y2-y1/x2-x1. y2 is your second y point, 4, and y1 is your first y point 0. same with x2 and x1. Then, choose another two points from the same graph and sub it into the equation with your slope to solve for b. That's the equation for strawberries. you can do the same with blueberries.

3)Strawberries 3) The reason why strawberries is cheaper than berries is because 5 is less than 7 and and tht is y

OpenStudy (anonymous):

Thank you can you help me with more

OpenStudy (anonymous):

Yea sure

OpenStudy (anonymous):

And blueberries are cheaper. You can tell because while strawberries are 2,4 blueberries are 2,3 meaning the strawberries are 4 dollars and blueberries are 3

OpenStudy (anonymous):

WAIT blue berries are cheaper

OpenStudy (anonymous):

No strawberries are cheaper

OpenStudy (anonymous):

No, you should check again. blueberries are cheaper... cost is on the left side of the graph while weight is at the bottom

OpenStudy (anonymous):

no, the blueberries are cheaper. choose any two points. for x=2, the blueberries are $3 while the strawberries are $4. for x=4, blueberries are $6 and strawberries are $8. therefore blueberries are cheaper.

OpenStudy (anonymous):

thany all for helping me

OpenStudy (anonymous):

it may look like the strawberries are cheaper near the end of the graph, but that's only because the strawberry line hasn't been extended to where the values of x ends for the blueberries.

OpenStudy (anonymous):

Acually u are right @iishineontheinside and @noneyabusiness I got it messed up srry @PlanSlam

OpenStudy (anonymous):

its ok your cool @Mesopretty

OpenStudy (anonymous):

y=mx+b is slope intercept form. m is the slope. so for a) y=3.5x, what's the m of the equation? and m is always with x.

OpenStudy (anonymous):

it's all good :) @Mesopretty

OpenStudy (anonymous):

y=mx+b is slope intercept form. m is the slope. so for a) y=3.5x, what's the m of the equation? and m is always with x.

OpenStudy (anonymous):

can you help me with that question Guys :D

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

if m is always with x, and the equation is y=3.5x, what's m?

OpenStudy (anonymous):

for y=mx+b

OpenStudy (anonymous):

can you help me with number 2

OpenStudy (anonymous):

Y=mx+b

OpenStudy (anonymous):

b is the y intercept. but since there is no b in y=3.5x, that means the y-intercept is...

OpenStudy (anonymous):

Wait im getting confused can you guys but the answers in order please

OpenStudy (anonymous):

In one message

OpenStudy (anonymous):

okay, so for a) it's asking for the slope. a) y=mx+b is the standard slope intercept equation. The equation is y=3.5x. m is always with x. what's the slope? b) it's asking for the y intercept. the y intercept is the value of y when x is 0. put 0 in for x in the equation to find the y intercept. c) In what situations can this equation be used, hypothetically?

OpenStudy (anonymous):

1) 3.5 2) the y intercept is o because there is no y in the equation leaving it to be 0 3) Sarah is at her first job ever. She is excited for her very first paycheck, so she tries to figure out approximately how much she will make. She earns 3.50 an hour. She will work 40 hours. so she makes 140 dollars.

OpenStudy (anonymous):

Ok so 1)3.5 2)The y intercept is O because there is no y in the equation and it will be 0 3) In what situations can this equation be used, hypothetically?

OpenStudy (anonymous):

thax :)))

OpenStudy (anonymous):

Welcome this jst takes a lot of thinking

OpenStudy (anonymous):

Is tht all
