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)

Which of the following is a linear function? (89 POINTS)HURRY PLSSSSS
Dennis_Churaev [7]
<h3>Solution:</h3>

A linear function is a straight line formed on a coordinate plane.

<u>To classify an equation as a linear function:</u>

  • It must not have any exponent in the equation.
  • If there is a fraction, the denominator of that fraction must not multiply by x.

If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.

<u>Option A - y = x³ + 1:</u>

  • This equation has an exponent in the variable x. Hence, this is a non-linear function.

<u>Option B - 5x/6 = y - 4:</u>

  • This equation has no exponents in the equation. Hence, this is a linear function and also our answer.

<u>Option C - y = 8x²</u>

  • This equation has an exponent in the term 8x². Hence, this is a non-linear function.

<u>Option D - y = 1/5x</u>

  • The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.

Hence, Option B is correct.

3) determine the missing side length <br><br> Pls don’t put the answer in a link
11Alexandr11 [23.1K]

Answer:

7 cm

Step-by-step explanation:

Here is how I solve these problems:

Halve of 6 is 3

10 minus 3 is 7

you subtract 3 from 10 because when you collapse the side (10) onto that side other side (let us call it x), x is shorter that 10 by halve the height.
