Voris made 80 cookies this week. She baked 4 less than three times the total she made last week. Which equation, when solved for
x, gives the number of cookies she baked last week?
3x - 80 = 4
3x + 80 = 4
3x - 4 - 80
3x + 4 = 80

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
