Slav-nsk [51]3 years ago
6 0

Answer:

  x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

  80 - x = 90 - 2x

  x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.

A linear function has a slope of 4 and a y-intercept of (0,-8). What is the x-intercept of the line?
miss Akunina [59]

Answer:

The answer to your question is 2 or (2, 0)

Step-by-step explanation:

Data

slope = m = 4

y-intercept = -8

Process

1.- Write the equation of the line in the slope y-intercept

                    y = mx + b

In this equation:

m = slope

b = y-intercept

-Substitution

                   y = 4x - 8

2.- To find the x-intercept, consider that y = 0 and solve for x.

                   0 = 4x - 8

                   4x = 8

                     x = 8/4

                    x = 2    or (2, 0)
