Answer:
Step-by-step explanation:
-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
You can find the slope of a line by looking at the number that has an X next to it.
for example
y=2x+5
the slope is = 2
