Question

Okay I'm almost finished, Can you guys check this one for me?? Thank YOU!!

12. What is an equation for the line with slope 2/3 and y-intercept 9?

a.y=2/3x <--
b. y=9x
c.y=2/3x+9
d. y=9x +2/3

I think I have got it wrong but i'm not sure and the other answers don't make sense with the question to me?

Answer 1

do you know slope-intercept form?

Answer 2

the equation will be of the form y = mx + b
where m = slope and b = intercept on the y axis

Answer 3

It is actually C.

y=2/3*x+9

Multiply (2)/(3) by x to get (2x)/(3).
y=(2x)/(3)+9

To find the slope and y intercept, use the y=mx+b formula where m=slope and b is the y intercept.
y=mx+b

Using the y=mx+b formula, m=(2)/(3) and b=9.
m=(2)/(3), b=9

Answer 4

um i learned it but i don't understand it at all

Answer 5

Thank you all of you!

Answer 6

welcome :D

Answer 7

yw

Answer 8

yw, but what part don't you understand? it is a really important concept so maybe we can help you with it

Answer 9

well i know when you are trying to find the slope on a graph you do rise over run and see how far each point is away from each other. Is that right?

Answer 10

yep, so if i gave you two points, could you calculate the slope?

Answer 11

the line will look something like this
