Answer:
y=1/2x-4
Step-by-step explanation:
You are given the slope, 1/2. So you can plug it into the equation (y=mx+b)
You also need to plug in the x and y coordinate your given so you'll have
-3=1/2(2)+b. Then you solve for b, which is -4. You now have your answer, y=1/2x-4.
Answer:
It should be 4

Answer:
1.375
Step-by-step explanation:
Answer:
(0, -3)
Step-by-step explanation:
y = 3x - 3
y = x - 3
In the solution to the system of equations, y is the same number for both of those functions. So 3x - 3 = x - 3.
Then solve for x:
3x - 3 = x - 3
Add 3 to both sides
3x = x
Subtract x from both sides
2x = 0
Divide both sides by 2
x = 0
Now that you have x, substitute it in one of the equations:
y = 3x - 3
y = 3(0) - 3
y = -3
x is 0 and y is -3, so the solution to the equation is (0, -3)
