The first thing I should do with these two points is find the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (-1 - 7)/(-9 - -9)
m = -8/0
The slope is undefined. We cannot divide by 0. This makes sense because the points (-9, 7) and (-9, -1) would be right on top of each other. This is a vertical line that has an x-intercept at -9.
Your equation would be x = -9.
Answer:
-14
Step-by-step explanation:
-8(2)-[3(-5)-(-1)+4(2-6)]+4(-7)
opening the brackets
-8(2)-[-15+1+4(-4)]+4(-7)
-8(2)-[-15+1+4(-4)]+(-28)
-8(2)-[-15+1+(-16)]-28
-16-[-15+1+-16]-28
-16-[-15-16+1]-28
-16-[-31+1]-28
-16-[-30]-28
-16+30-28
-16-28+30
-44+30
-14
D is correct :D
Tell me if I got it wrong :l
