Question

(5,-2) and m = -4/5
what is this in slope intercept form? (y=mx+b)

Answer 1

y = -4/5x + 2

Explanation:

y = -4/5x + b

(-2) = -4/5(5) + b

-2 = -4 + b

2 = b

Answer 2

Answer: y=-4/5x+2

Explanation:

To write in slope-intercept form, you have the slope and y-intercept. Since we are given slope, you want to use the given point to find the y-intercept.

-2=-4/5(5)+b [multiply]

-2=-4+b [add both sides by 4]

b=2

Now that we have the y-intercept, we know the equation is y=-4/5x+2.
