ahhhhhh...i cant seem to figure out how you graph an equation(linear)

Question

a linear equation is y=mx+b right.

so m is the slope, b is y intercept. x and y are points. so what you can do is substitute a point to get another.

for x: y=5x+3

For x=1, y=8 so (1,8)

for x=0, y=3 so (0,3)

so on.... then graph all these points and connect
