Write the slope-intercept form of the equation of each line

slope intercept form- y=mx+b

m=slope

b=y-intercept

how to find slope= rise/run

how to fine y-intercept= go straight down the y axis (up and down in the center of the graph) until you come across a point

slope=3

y-intercept=-1

answer= 3x-1

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
