Question

Find the slope and the y-intercept of the equation x − 4(y + 1) − 5 = 0.

Answer 1

let x=0, solve for y .... that is the intercept

let x=1, solve for y again ... the difference the y values from x=0 to x=1 will define the slope.

Answer 2

Hi
Look :
if we have :
2*(2+3)=2*2+2*3
or : 2(a+8)=2*a+2*8=2a+16
k ?
So :
− 4(y + 1) = (-4)*y+(-4)*+1=-4y-4
( look :
(-)*(-)=+
(+)*(+)=+
(_)*(+)=- )
so we have :
x − 4(y + 1) − 5 = 0=>x-4y-4-5=0
Get it in standard form . it s :
y=mx+d ;so first we should have y alone :
x-4-5=4y
x-9=4y
delete 4 in 4y ; divided 4
x/4-9/4=y=>1/4x-9/4=y
m x + d = y
So we have :
slope : that number you see before x means 1/4
y-intercept :is that -9/4
Got it ?;)
