Enter the slope-intercept equation of the line that has a slope of -5 and y-intercept (0,8)

Slope-intercept form is y = mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept. Because we are given these values, all we have to do is plug in the given values into the equation for their respective variables.

y = mx + b

y = -5x + 8

Therefore, your answer is y = -5x + 8.

Hope this helps!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
