Question

6. 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). (1 point

Answer 1

y = 5x + 1
the slope here is 5
a parallel line will have the same slope

now we will use y = mx + b
(4,5)...x = 4 and y = 5
slope(m) = 5
now we sub, and since we already know the slope, we will find the y intercept, which is b.
5 = 5(4) + b
5 = 20 + b
5 - 20 = b
15 = b

so our parallel equation is : y = 5x + 15
