Question

How would you write y-7=-3/4(x+5) from point slope form to slope intercept form ??

-3/4 is a fraction in the equation btw. Thank you

Answer 1

y - 7 = -3/4(x + 5) -- distribute through the parenthesis
y - 7 = -3/4x - 15/4 -- add 7 to both sides
y = -3/4x - 15/4 + 7 -- common denominator is 4
y = -3/4x - 15/4 + 28/4
y = -3/4x + 13/4 <== slope intercept form

any questions ? Basically, all you do is solve for y by moving everything else over to the other side.
