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)

Hey there!

Assuming that $"f" = y$

So, let's solve your function, shall we?

$y(-1) = 2 \\ \\ \\ -y= 2 \\ \\ DivideBy(-1) \\ \\ \\ \frac{-y}{1} = \frac{2}{-1} \\ \\ \\ CancelOut: \frac{-y}{1} \\ \\ \\ Keep: \frac{2}{-1} \\ \\ \\ \\ Answer: y = -2 (option D)$

Good luck on your assignment and enjoy your day!
