7x-5y=105

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.

-5y=105-7x

Divide each term by -5 and simplify.

Divide each term in -5y=105-7x by -5.

-5y-5=105-5+-7x-5

Cancel the common factor of -5.

Cancel the common factor.

-5y-5=105-5+-7x-5

Divide y by 1.

y=105-5+-7x-5

y=105-5+-7x-5

Simplify 105-5+-7x-5.

Simplify each term.

Divide 105 by -5.

y=-21+-7x-5

Dividing two negative values results in a positive value.

y=-21+7×5

y=-21+7×5

Reorder -21 and 7×5.

y=7×5-21

y=7×5-21

y=7×5-21

Rewrite in slope-intercept form.

y=75x-21

y=75x-21

Using the slope-intercept form, the y-intercept is -21.

b=-21
