we can use the Pythagorean theorem to solve this problem

x^2 + 4^2 = 5^2

x^2 + 16 = 25

x^2 = 9

x = +/- 3

we take only the positive value because a length can‘t be negative

x = 3

write a equation in slope-intercept form for the line that is parallel to y=2x-8 and passes through the point(1,5).

Brilliant_brown [7]

Answer:

y = 2x + 3

Step-by-step explanation:

y = 2x - 8 passes through ( 1,5 )

y = 2x + 3 is parallel to y = 2x - 8 because it has the same m( 2x)

and it also passes through ( 1, 5 )
