ANSWER

Point-slope form:

y + 5 = -3(x - 1)

Slope-intercept form;

y = - 3x - 2

EXPLANATION

The point-slope form of a line is given by:

y-y_1=m(x-x_1)

We need to find the slope using the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Let us substitute the point (1, –5) and (–3, 7).

This implies that,

$m = \frac{7 - - 5}{ - 3 - 1}$

$m = \frac{12}{ - 4} = - 3$

The point slope form now becomes,

y - - 5 = - 3(x - 1)

y + 5 = -3(x - 1)

To find the slope intercept form, we expand to obtain;

y = - 3x + 3 - 5

y = - 3x - 2
