slope? intercept?

Question

Find the slope and the y-intercept.y = –4x

Find the y-intercept.
–x + 2y = 4
A) (–4, 0)
B) (0, 2)
C) (2, 0)
D) (0, –4)

Answer 1

slope = -4 and y-intercept = 0

2y= x + 4
y = x/2 + 2
y-intercept is (0,2)

Answer 2

First part.

y = mx + b where m is the slope and b is the y-coordinate of the y-intercept.

slope = -4, y-intercept = 0

Second part.

the y-intercept is found by substituting x=0 into the equation and solving for y.

You get the point (0,2).

Answer 3

slope -4
y intercept x=0

for the second one plug y=0 so x=-4 so point A)(-4,0)

Answer 4

y-intercept= the point where the line intersects on the graph

slope= rise/run


an easy way to fine y-intercept: when "X" equals "0", what does "Y" equal?

when "X" equals "1", what doees "Y" equal?


the answer is B if you were wondering.

Answer 5

solve for y...y=2 + (1/2)x...so slope = 1/2..y-int= 2
