Answer:
A
Step-by-step explanation:
Given the 2 equations
x = 3 - y → (1)
5x - 12 = y → (2)
Substitute x = 3 - y into (2)
5(3 - y) - 12 = y ← distribute and simplify left side
15 - 5y - 12 = y
3 - 5y = y ( add 5y to both sides )
3 = 6y ( divide both sides by 6 )
= y, that is
y = 0.5 → A
So as you can see, -3 is the y-intercept. You would make a point on (-3,0) first. Then from the point, you would go up 1 and go right 2 because the slope is a positive 1/2 slope.
Answer:
The constant of variation is 3
Step-by-step explanation:
Given.
And y is directly related to x
∝ 
Here k is constant of variation
--------------(1)
Put the and value in equation 1.
So, the constant of variation is 3.
Answer:
your answer should be x = -3
