You can put this solution on YOUR website!
y is always the y-axis.
x is always the x-axis.
.
get y to the left and x to the right in y=mx+b form.
m = slope
b = y-intercept
.
3x -y = 3
.
subtract 3x from both sides
-y = -3x +3
.
multiply by -1
y = 3x -3
.
the slope = 3
the y-intercept is (0,-3).
.
the x-intercept occurs where y=0
0 = 3x -3
3x = 3
x = 1
(1,0)
.
with two points you can draw the line.
.
