Answer:

d = 13

Step-by-step explanation:

So first we collect like terms

-18d - (-5d) + 15d + (-15) = 11

-18 + 5d + 15d - 15 = 11

2d - 15 = 11

Add 15 to both sides

2d = 26

Divide both sides by 2

d = 13

tester [92]

Answer:

slope = - $\frac{2}{7}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 5, 7 ) and (x₂, y₂ ) = (2, 5 )

m = $\frac{5-7}{2-(-5)}$ = $\frac{-2}{2+5}$ = - $\frac{2}{7}$
