Answer:

Infinite Solutions.

Step-by-step explanation:

$m+7=3+m+4$

Subtract m from both sides:

$m+7-m=3+m+4-m$

$7=3+4$

$7=7$

Both sides are equal.

This means that the value of m does not affect the end result of 7 = 7, which is true. Thus, there are infinite solutions as any value of m will still make the equation true.

Find the slope (-8,10) (8,15)

Novosadov [1.4K]

<h3>Question:</h3>

find the slope (-8,10) (8,15)

<h3>Answer:</h3>

m = $\frac{5}{16}$

<h3>Step-by-step explanation:</h3>

Use the slope formula $\frac{y2-y1}{x2-x1}$

(x2,y1) = (-8,10) , (x2,y2) = (8,15)

m = $\frac{15-10}{8-(-8)}$

m = $\frac{5}{16}$
