Math
4x-7y=21
Rewrite in slope-intercept form.
Tap for more steps…
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Subtract 4x from both sides of the equation.
-7y=21-4x

Divide 21 by -7.
y=-3+-4x-7
Dividing two negative values results in a positive value.
y=-3+4×7
y=-3+4×7
Reorder -3 and 4×7.
y=4×7-3
y=4×7-3
y=4×7-3
