Which of these is a point-slope equation of the line that is perpendicular to y-25=2(x-10) and passes through (-3,7)
OLEGan [10]
Y = 2x +13

We know the slope to be 2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and  the known point. 

y = mx + b ----> Input known values
7 = (2)(-3) + b ---> Multiple
7 = -6 + b ----> Subtract 3 from both sides
13 = b

Now we can use the y-intercept found and the slope to write the equation above.
