Find the equation of the line using the point-slope formula. write the final equation using the slope-intercept form.
the x-intercept is 1, and
(x, y) = (−2, 12)
is a point on the line

you can confirm this for yourself. Substitute 1, see if y = 0;

do the same for x=-2; see if y = 15

Step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
