Question

Please help!!! What is the equation of the line in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

y=-x-40

• Explanation:

Slope intercept form is y=mx+b

slope=rise/run

slope= -40/40 = -1

y-y1=m(x-x1)

y-(-40)= -1(x-0)

y+40=-x+0

y=-x+0-40

y=-x-40

hope that helps?

Answer 2

y = x - 40

Explanation:

Points on the graph: (0, -40) and (60,20)

Slope:

m=(y2-y1)/(x2-x1)

m=(20+40)/(60-0)

m=60/60

m = 1

Slope-Intercept

y - y1 = m(x - x1)

y + 40 = 1(x -0)

y + 40 = x

y = x - 40
