Answer:
(four being the slope)
Step-by-step explanation:
So lets use
ΔY/ΔX
or the y2-y1 over x2-x1


Therefore, the slope is 4
Answer:
37
Step-by-step explanation:
tan(theta)=perpendicular/base
tan(theta)=3/4
theta=arctan(3/4)=37
We need to solve for x. Let's try problem b:

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

Since this is true, your answer would be:
All real numbers
------------------------------------------------------------------
Let's solve for problem c:

Let's isolate x, so subtract 1 from both sides:

Since x can't have a coefficient, divide both sides by 3:


So, only the value of 14 would make this equation true.
------------------------------------------------------------------
Let's try problem d:

Let's get our whole numbers on the right side. Add 1 to both sides:

Subtract 4x from the right side on both sides:

Since this is not true, your answer would be:
No solution
