Graph each line using its y-intercept and slope.?

Question

Graph each line using its y-intercept and slope.

y + 4x = 8

Answer 1

y intercept (0,8)

slope -4/1

x intercept (2,0)

Answer 2

You want to rewrite this in slope intercept form:

y = mx + b

Where m equals the slope and b equals the y-intercept.

y = -4x + 8

Now you know the slope = -4

And the y-intercept = (0,8)

Now you can easily graph this equation using just these two pieces of information.

Mark a point at (0,8) and then go down four points and over (right) 1 and make another dot, then from there go down 4 points and over (right) 1 and make another dot. Now line up these three dots and draw your line, and you've graphed this equation using its y-intercept and slope!

Have a good day!

Answer 3

y=mx+b

y= -4x+8

X......Y

-2...16

-1...12

0.....8

1.....4

2.....0

I think that's right, but just make sure the slope is positive!
