Step-by-step explanation:

Let's solve your inequality step-by-step.

−50−(−9d+7)>−d+10+9d

What is the slope of the line which passes through (4, 7) and (2, 3)? (5 points)

Basile [38]

Answer:

slope = 2

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 ) = (2, 3) and (x₂, y₂ ) = (4, 7)

m = $\frac{7-3}{4-2}$ = $\frac{4}{2}$ = 2
