What are the X- and y- intercepts of the line? 2x + 3y = -12

Lera25 [3.4K]

Subtract 2x from both sides.

3y = - 2x - 12

Divide every term by 3 to get the y-variable by itself.

y = - 2/3x - 4

Since the equation is not in slope-intercept form (y = mx + b), your y-intercept is just the number in the b slot. Y-intercept is - 4 or (0, - 4).

Now to find your x-intercept, plug in 0 where the y-variable is and solve for x.

0 = - 2/3x - 4
4 = - 2/3x

Multiply both sides by - 3/2 to isolate the variable.

4(- 3/2) = x
- 12/2 = x
- 6 = x.

Your x-intercept is - 6 or (- 6, 0).

-0.2x^2+0.9x+0.6=y<br>What's the vertex form for this equation?

Answer: y = -0.2(x - 2.25)² + 1.6125

<u>Step-by-step explanation:</u>

$y = -0.2x^2 + 0.9x + 0.6\\\\y - 0.6 = -0.2x^2 + 0.9x\\\\y - 0.6 =-0.2(x^2-4.5x)\\\\y-0.6+\underline{(-0.2)(2.25)^2}=-0.2(x^2-4.5x+\underline{2.25^2})\\\\y-0.6-1.0125=-0.2(x-2.25)^2\\\\y-1.6125=-0.2(x-2.25)^2\\\\y=-0.2(x-2.25)^2+1.6125$
