Answer:
The equation of the line is y = 2x + 3
Step-by-step explanation:
In order to find this, we first need to find the slope. For that we use slope intercept form. 
m(slope) = (y2 - y1)/(x2 - x1)
m = (15 - 7)/(6 -2)
m = 8/4
m =2
Now that we have this, we can use the slope and either point in slope-intercept form to get the equation. 
y - y1 = m(x - x1)
y - 7 = 2(x - 2)
y - 7 = 2x - 4
y = 2x + 3
