Will give medal

Answer 11

y = -2

Answer 12

Simply for any value given for x , y remains constant ( -2 )

Answer 13

i think the answer is "C" because the y which is 2 in the equation hits 2 on the graph and the slope -3 maches the graph be cause the points on the graph goes down three and across 1

Answer 14

@green_1 , Isn't the slope zero ?

\[\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{ -2 - (-2) }{ x_{2} - x_{1} } = 0\]

Answer 15

the equations are already in slope intercept form. all you have to do is see where the line on the graph hits the y axis, which is 2 and to find the slope all you have to do is use rise over run when you are following the points showed and the points in between them.

Answer 16

i think you would use that equation on finding the equation for ordered pairs.

Answer 17

"to find the slope all you have to do is use rise over run when you are following the points showed and the points in between them."

The slope is zero as the line is horizontal.

Answer 18

@green_1 , You're right, he could use the equation to find the it.

y = mx + b

we found that slope = 0 , y intersection is -2

b = -2
m = 0
so y = -2
