The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m = -3 and the y-intercept b = 1. Substitute:

y=-3x+1

It is a linear function. We need only two points to plot the graph.

Select two values of x. Put them in the line equation and calculate the values of y.

for x = 0:

$y=-3(0)+1=0+1=1\to(0,\ 1)$

for x = 1:

$y=-3(1)+1=-3+1=-2\to(1,\ -2)$
