Find the equation of the para bola that has zeros of x = -2 and x = 3 and a y-intercept of (0,-30)

Answer:

y = 5x^2-5x-30

Step-by-step explanation:

A parabola with x-intercepts at (-2,0) and (3,0) has the equation

y = a(x+2)(x-3)

where a is to be determined.

We know that it passes through the point (0,-30), so

-30 = a(0+2)(0-3) = -6a

Therefore solve for a to get

a = 5

y = 5(x+2)(x-3)

y = 5(x^2-x+6)

y = 5x^2-5x-30

Y=1/3x what is the slope
Karolina [17]

Answer:

Slope = \frac{1}{3}

Step-by-step explanation:

The equation for finding slope is:

y = mx+b

In the equation, m is the slope, x is the x-intercept, and b is the y-intercept. The number next to x is ALWAYS the slope.

Your equation:

y = \frac{1}{3} x

The number(fraction) next to x is \frac{1}{3}. Therefore, your answer will be \frac{1}{3}
