Answer: OPTION C.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Given the system of equations:

Solve for "y" from the first equation in order to write it in Slope-Intercept form:

Since the lines have different slopes, they cannot be parallel or coincident. Therefore, they are Intersecting.

Answer:
n= 24
Step-by-step explanation:
n +7 =31
Both side -7
n+7 -7 =31-7
n= 24
Y intercept: when x = 0
(0, y)
On the graph it is (0,-5)
Solution: y intercept is (0,-5)
Answer:
I think x=8
Step-by-step explanation:
5(x+7)+15=90
90 because it's a 90 degree angle
5x+35+15=90
5x+50=90
5x=40
x=8
