Answer:
y = 2x + 6
Step-by-step explanation:
The equation for a linear line is y = mx + c.
We know we want it to cross the y-axis at 6, so the y-intercept (c) can be assumed to be 6.
If we substitute in the x that we want, we end up with this:
0 = m(-3) + 6
m = 2
So now we can form the equation:
y = 2x + 6
