Question

Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.

Answer 1

y = mx+b

y = 4x + b ... Plug in the given slope, m = 4

-1 = 4(-3) + b ... Plug in x = -3 and y = -1 from the given point (-3,-1)

Now solve for b

Answer 2

Tell me what you get

Answer 3

y=4x-11

Answer 4

close, but not quite

Answer 5

y = mx+b

y = 4x + b ... Plug in the given slope, m = 4

-1 = 4(-3) + b ... Plug in x = -3 and y = -1 from the given point (-3,-1)

-1 = -12 + b

-1+12= b

11 = b

b = 11

The 11 is positive since -1+12 is the same as 12-1

Answer 6

y=4x+11

Answer 7

you got it

Answer 9

alright

Answer 10

What is Correlation?

Answer 11

it's like a connection between two or more variables

Answer 12

but it's not a strong connection like one causes the other

ex: there is a correlation between studying and getting good grades. As one goes up, the other goes up (but the two aren't directly connected)

Answer 13

Ex House Address vs test score

Answer 14

if you increase your house address, will that change your test score? How about if you decrease your house address?

Answer 15

Okay AGE VS COMMUTE TIME TO SCHOOL

Answer 16

same question: if you change your age, will that change the commute time?

Answer 17

but as a positive correlation

Answer 18

not sure what you mean

Answer 19

That Alright Last Question How Would You Writethe equation of the line in slope-intercept form with a slope of -5 and a y-intercept of -1.

Answer 20

y = mx+b is the general equation of a line

Answer 21

where m is the slope and b is the y-intercept

Answer 22

That's All

Answer 23

the slope is -5 so m = -5

what is b?

Answer 24

-1

Answer 25

so

y = mx+b

becomes

y = -5x - 1
