Graph Using a Table of Values y=0.77x+91

$y = 0.77 x + 91$

Step 1

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = 0.77 (- 2) + 91$

Step 2

Simplify $0.77 (- 2) + 91$ .

Multiply $0.77$ by $- 2$ .

$y = - 1.54 + 91$

Add $- 1.54$ and $91$ .

$y = 89.46$

Step 3

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = 0.77 (- 1) + 91$

Step 4

Simplify $0.77 (- 1) + 91$ .

Multiply $0.77$ by $- 1$ .

$y = - 0.77 + 91$

Add $- 0.77$ and $91$ .

$y = 90.23$

Step 5

Substitute $0$ for $x$ and find the result for $y$ .

$y = 0.77 (0) + 91$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 0.77 (0) + 91$

Simplify $0.77 (0) + 91$ .

Multiply $0.77$ by $0$ .

$y = 0 + 91$

Add $0$ and $91$ .

$y = 91$

Step 7

Substitute $1$ for $x$ and find the result for $y$ .

$y = 0.77 (1) + 91$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 0.77 (1) + 91$

Simplify $0.77 (1) + 91$ .

Multiply $0.77$ by $1$ .

$y = 0.77 + 91$

Add $0.77$ and $91$ .

$y = 91.77$

Step 9

Substitute $2$ for $x$ and find the result for $y$ .

$y = 0.77 (2) + 91$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 0.77 (2) + 91$

Simplify $0.77 (2) + 91$ .

Multiply $0.77$ by $2$ .

$y = 1.54 + 91$

Add $1.54$ and $91$ .

$y = 92.54$

Step 11

This is a table of possible values to use when graphing the equation.

$\begin{array}{c} x & y \\ - 2 & 89.46 \\ - 1 & 90.23 \\ 0 & 91 \\ 1 & 91.77 \\ 2 & 92.54 \end{array}$
