A radio telescope has a parabolic surface, as shown below. A parabola opening up with vertex at the origin is graphed on the coordinate plane. The height of the parabola from top to bottom is 1 meter and its width from left to right is 8 meters. If the telescope is 1 m deep and 8 m wide, how far is the focus from the vertex?

Answer:
y+2=3(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(7-(-2))/(2-(-1))
m=(7+2)/(2+1)
m=9/3
m=3
y-(-2)=3(x-(-1))
y+2=3(x+1)

What is the slope of the equation?
-7
-5
2
7
Answers
m is the slope and b is the y-intercept.
y-intercept is when x is 0 and x-intercept is when y is 0. So if x is 0, y=m(0)+b which is y=b. So on the graph y will be b when x is 0.
So in y=7x+2, 7 is the slope and 2 is the y-intercept.
y = mx + b
where: m = slope; b = y-intercept.
Using the above format,
y = 7x + 2
m = 7 ; b = 2
The slope of the equation is 7.
The y-intercept of the equation is 2.
