a point =(x1,y1)

slope=2
point= (-1,3)
y-3=2(x+1)
y-3=2x+2
y=2x+5
test given points

A.
(1,5)
5=2(1)+5
5=7
false

B.
(1,4)
4=2(1)+5

The answer would be D. If you graphed this line, you would find that one of the y intercept matches choice D. You can also put this into the slope-intercept equation which is y= 2x +5. So if you plug in the point (0,5), it will look like this: 
5=2(0)+5. The 2 will be 0 so it ends up being 5=5 which is true for this line.

Answer:

$25.57

Step-by-step explanation:

First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.

5.29 * 2 = $10.58

Then you want to add $10.58 and $14.99 together.

$10.58 + $14.99 = $25.57
