Best Answer

The standard form for an equation that is linear is

y = mx + b where m = slope and b = y intercept

If you know slope and intercept, simply plug in different values of x and solve y and graph

For example

if y = 3x + 4

when x =0 y = 4

when x =1 y = 7

when x =2 y = 10

plot points (0,4) (1,7) (2,10) on graph
