Basing on the description, a parabola opening up with vertex at origin, the formula with vertex at origin is used, x^2 = 4py. p is the focus and so with the dimensions given, we obtain a 0.25 and that is the distance of the focus to the vertex.

I need to find the slope and b <br> Y=mx+b <br> HELP ME

Naddika [18.5K]

Answer:

$y=-\frac{4}{3}x+20$

Step-by-step explanation:

stupid enough

y=mx+b

$\frac{y1-y2}{x1-x2}$

slope = 16-12/3-6

-4/3

$y=-\frac{4}{3}x+b$

plug in x and y

16=-4/3(3)+b

b=20
