Answer:
y-7=3(x-9)
Step-by-step explanation:
It appears they want your answer in point-slope form, which is identified by the equation y-y1=m(x-x1)
Step 1: Find the slope (m)
m=(y2-y1)/(x2-x1)
m=(-8-7)/(4-9)
m=(-15)/(-5)
m=3
The slope is m=3
Step 2: Plug in m, y1, and x1
y-y1=m(x-x1)
y-7=3(x-9)
Therefore our final equation is y-7=3(x-9)

Answer:
B
Step-by-step explanation:
I hope this helps!
Answer:
x + y = 4 Equation 1
y = 2x -1 Equation 2
-2x + y = -1
x + y = 4
Subtract
You will get
- 3x = -5
Divide by -3
-3x / -3 = - 5 /-3
x = 5/3
Substitute x into equation 1
x + y = 4
x = 5/3
5/3 + y = 4
y = 4 - 5/3
y = 7/3
x = 5/3 y = 7/3
Hope this helps.
