Answer:
3)x=−9 and x=4
4)x=−12 and x=−5
5)x=8 and x=14
6)x=−7 and x=3
7)x=-1 2/3 and x = 1/4
8)x=2/5
Step-by-step explanation:
Hope this helps
Start on -7 since it is the y intercept(b). 4/1 is the slope. So from seven you would go up 4 right 1.
Perpendicular = opposite sign and reciprocal slope
Slope would be 3
Y = 3x + b, plug in point
9 = 3(5) + b, b = -6
Solution: y = 3x - 6
