Write the linear equation -7x 8y=-1 in slope-intercept form

A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.

Assuming the space inbetween -7x and 8y is a plus sign.

To get the equation in the right format, one must do the following:

8y=7x-1
y=7/8x-1/8

And theres your answer!

Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)

The answer would be $68.04
