Math
7x-9y=-15
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 7x from both sides of the equation.
-9y=-15-7x
Divide each term by -9 and simplify.

Factor -3 out of -15.
y=-3(5)-9+-7x-9
Cancel the common factors.
Tap for more steps…
Factor -3 out of -9.
y=-3⋅5-3⋅3+-7x-9
Cancel the common factor.
y=-3⋅5-3⋅3+-7x-9
Rewrite the expression.
y=53+-7x-9
y=53+-7x-9
y=53+-7x-9
Dividing two negative values results in a positive value.
y=53+7×9
y=53+7×9
Reorder 53 and 7×9.
y=7×9+53
y=7×9+53
y=7×9+53
Rewrite in slope-intercept form.
y=79x+53
y=79x+53
Using the slope-intercept form, the y-intercept is 53.
b=53
