y - y1 = m(x - x1)

y - -3 = 3(x - 1)

y + 3 = 3x - 3

y = 3x - 3 - 3

y = 3x - 6

y = 3x - 6

Thie equation is in slope-intercept form (y = mx + b)

The y-intercept is -6 .... ((0, -6) is one point on the line.

It is given that (1, -3) is also on the line. So to graph, plot those

2 points and connect them with a line.
