Question

write an equation in the form y=mx+b for the line that has a slope of 4 and contains the point (-1,-3)

Answer 1

\[\huge~y-y_1=m(x-x_1)\]
m=slope
(x1,y1)

Answer 2

We know that the slope is 4
so m= slope
We know x1 = -1
we know y1=-3
now just plug those into the formula :)

Answer 3

2

Answer 4

huh? 2 for what?

Answer 5

i plugged it in for you :) now solve
\[ \huge~y+3=4(x+1) \]

Answer 6

Do you know what to do after this?

Answer 7

multiply 1 from 4

Answer 8

?

Answer 9

no distribute

Answer 10

how do i distribute

Answer 11

4(x+1)
4*x=?
4*1=?

Answer 12

4

Answer 13

y+3=4x+4
now we need to isolate y so we need to subtract
4-3=?

Answer 14

1

Answer 15

good so our final answer would be??

Answer 16

y=4x+1

Answer 17

good
