Answer:
3-1=2
Step-by-step explanation:
Slope intercept form:
y=mx+b
m=slope
b=y-intercept
y=-3x+b
Plug in the given coordinate and solve for b (12,5)
5=-3(12)+b
5=-36+b
41=b
Final answer:
<span>y=-3x+41<span>

Answer:
x = 6
Step-by-step explanation:
The line of symmetry for the parabola written in the form y=ax²+bx+c is given by the equation x=-b/(2a).
__
Comparing your equation to the above form, we see ...
Then the line of symmetry is ...
x = -b/(2a) = -(-12)/(2(1)) = 6
The line of symmetry is x=6.
