The y-intercept occurs when x=0 so one point is: (0, 2)

and the other point is (-3, 7)

Slope = difference in y divided by difference in x

Slope = (2 -7) / (0, --3)

Slope =  -5 / 3

Slope = -1.66666666

Step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
