Question 8 of 8

Answer 1

Answer:

$y = 2x + 2$

Step-by-step explanation:

To find the slope you look at how much the line rises after going 1 unit to the right. In this equation it rises 2 after going over, or running, 1 unit to the right. So the rise over run is 2 over 1. It can be represented in a fraction 2/1. The slope is the rise over run, being 2.

The constant in the equation, or the y-intercept, is the point where the line intersects the y axis, the dark vertical line. You can count how many units it is from the origin where the 2 black lines intersect. The y-intercept in this is 2.

The slope is the number bedfore the x and the y intervept is the constant after the x.

Answer 2

Answer:

y = -2x + 2

Step-by-step explanation:

y=mx+b

find slope(m) first:

choose two points: (1,0), (0,2)

(y2-y1)/(x2-x1)

= (2-0)/(0-1)

= 2/-1

= -2
