the equation of line AB is y=5x+1. write an equation of a line parallel to line AB in slope-intercept form that contains point (4,5).

Question

ok...look at your equation y = 5x + 1. Can you tell me what the slope is ?

texaschic101 · Answer

I am in a good mood....slope is 5. Parallel line will have same slope.
Now use y = mx + b
slope(m) = 5
(4,5)  x = 4 and y = 5
now we sub and solve for b
5 = 5(4) + b
5 = 20 + b
5 - 20 = b
-15 = b
so your parallel line will be : y = 5x - 15
