Kiana wants to cover and area of her backyard with concrete patio stones in the shape of a right triangle each stone cost 0.42$ and covers 29.26 squares inches .Each square grid represents 1 square foot if R(1,1) E(7,9) and D(I5,3) what is the minimum number of stones Kiana should by to cover a right triangular area in her backyard show work below.

step-by-step explanation:

i believe the correct answer is b.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

you'll have to attache the image of the bar graph in order for us to answer : )
