Answer:

The value of y is 14

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have the points

[tex](-2, y)\ and\ (4, 6)[/tex]

[tex]m=-\frac{4}{3}[/tex]

substitute in the formula the given values

[tex]-\frac{4}{3}=\frac{6-y}{4+2}[/tex]

solve for y

[tex]-\frac{4}{3}=\frac{6-y}{6}[/tex]

Multiply by 6 both sides

[tex]-8=6-y[/tex]

[tex]y=6+8=14[/tex]
