Answer:

first answer is y = 2x + 2

second answer is y = 1/4x + 6

Explanation:

sooo to find the slope you can just count it but i feel like using the equation

y2 - y1 / x2 - x1

is better

so lets substitute

6 - (-6) / 2 - (-4)

6 + 6 / 2 + 4

12 / 6

y = 2x + b

to find b we substitute a point we did not use yet (-2, -2)

-2 = 2(-2) + b

-2 = -4 + b

b = 2

y = 2x + 2

second question:

we do the same thing

(-4, 5) (8, 8)

8 - 5 / 8 - (-4)

3 / 12

1/ 4

y = 1/4x + b

since the graph shows the y intercept (0, 6) we can input it into the equation

y = 1/4x + 6

i cant check it (with a point) because there are not a lot of exact points, but this should be the answer
