The formula to find a slope is m=(y2-y1)/(x2-x1)` `

Let's label the point (1, -3) as the (x1, y1). Label the point (3, 3) as the (x2, y2).

Plug in the points into the formula m=(y2-y1)/(x2-x1) 

                                                 m=(3-(-3))/(3-1)

                                                 m=6/2

                                                 m=3

The slope that passes through the coordinates (1, -3) and (3, 3) is 3.

Given the points are

(x_1,y_1) =(1,-3)

and

(x_2,y_2) =(3,3)

the slope of the line passing through the points is given as 

m = (y_2 - y_1)/(x_2 - x_1)

    = (3-(-3))/(3-1)

    = 6/2 = 3

so the slope is 3
