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)

Are all rhombuses parallelograms?
ss7ja [257]

Answer:

Yes

Step-by-step explanation:

All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares. The opposite interior angles of rhombuses are congruent. Diagonals of a rhombus always bisect each other at right angles.
