let us solve this

$y$ $y$ = -4 $(x - 15)$ $( x -15)$ +4

Using distributive property, we get

$y$ $y$ = -4 $(x - 15)$ $( x -15)$ +4

$y$ $y$ = -4.x - $4 . - 15$ $4.-15$ +4

$y$ $y$ = -4.x + $60$ $60$ +4

$y$ $y$ = - $4 . x$ $4.x$ + $64$ $64$

comparing with the equation y = mx + c , we get
the intercept 'c' is 64 and slope is -4

What is the x-intercept of y=−4(x−15)+4y=-4(x-15)+4?
