Find the slope of the line graphed in the diagram and choose the correct answer from the choices below. the two intercepts are (0, 2) and (.8, 0)

a) 2/5

b) 5/2

c) -2/5

d) -5/2

We can use the points (0, 2) and (0.8, 0) to solve.

Slope formula: y2-y1/x2-x1

= 0-2/0.8-0

= -2/0.8

= -2.5

= -5/2

Hope This helped! Good Luck!

they are simplified

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
