Question

Find the y value for the given slope.
1.) (2,y), (3,3) m=2
2.) (4,y), (6,3) m=-2
3.) (5,-1), (-2, y) m=1

Answer 1

We know that, 
$Slope = \frac{y_2-y_1}{x_2-x_1}$

1)  $\frac{3-y}{3-2} = 2$

3 - y = 2
y = 1

2)  $\frac{3-y}{6-4} = -2$

3 - y = -4
y = 7

3) $\frac{y+1}{-2-5} = 1$

y + 1 = - 7
y = -8
