Explanation:
You have the equation of a line in the point-slope form:

m - slope
(x₁, y₁) - point on a line
Convert the given equation to the slope-intercept form:

m - slope
b - y-intercept (0, b)
use the distributive property
subtract 1 from both sides

We only need two points to draw the line.
Choose two different x values. Put them in the line equation and calculate the y values:
for x = 0:

for x = 3:
