Answer:
The value of y is 6.
Step-by-step explanation:
To find the value of y, start by using the known information we have in the equation for slope. The equation is below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.
1/2 = (7 - y)/(2 - 0)
1/2 = (7 - y)/2
Now we can use cross multiplication to solve for y.
1/2 = (7 - y)/2
1*2 = 2(7 - y)
2 = 14 - 2y
-12 = -2y
6 = y
