Write an equation for the quadratic function that has one x-intercept at (-7, 0) and passes through (-4, -18).

The quadratic function has an x-intercept of (-7,0)

and passes through (-4,-18)

The gradient(m) of its graph is (-18 - 0) ÷ (-4 - -7) = -18/3 = -6

Taking a point (x,y) the equation is;

(y - 0) ÷ (x - -7) = -6

y = -6x - 42

yes. we do proportions in probabilities.
