Which statement best explains whether the table represents a linear or nonlinear function? Input (x) Output (y) −2 7 −5 4 −8 1 −
blsea [12.9K]

Answer:

The table represents a linear function because the rate of change is constant or all the points lie on a straight line.

Step-by-step explanation:

From the given table it is noticed that the line passing through the points (2,5), (4,10), (6,15) and (8,20).

The slope of the line is

m= y2-y1/x2-x1 = 10-5/4-2 = 5/2

The slope of line is . It means the value of y increased by 5 if the value of x increased by 2.

From the given points we can noticed that the value of y increased by 5 if the value of x increased by 2. So, the function has same slope for any two points.

Since the rate of change (slope) is same for all points, therefore the table represents a linear function.

If we plot these points on a coordinate plane and connect then we get a straight line. I means it is a  linear function.

Write an equation for the line passing through the given pair of points. give the final answer in standard form (-4,-2) and (3,-
Andrew [12]

Answer:

y = -2/7x - 22/7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-4, -2)

Point (3, -4)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-4+2}{3+4}
  2. Add:                              m=\frac{-2}{7}

<u>Step 3: Find y-intercept </u><em><u>b</u></em>

  1. Define:                    y = -2/7x + b
  2. Substitute:              -4 = -2/7(3) + b
  3. Multiply:                  -4 = -6/7 + b
  4. Isolate <em>b</em>:                 -22/7 = b
  5. Rewrite:                   b = -22/7

<u>Step 4: Write linear equation</u>

y = -2/7x - 22/7
