Question

Write the linear equation that gives the rule for this table.

x y
4 3
5 4
6 5
7 6


Write your answer as an equation with y first, followed by an equals sign.

Answer 1

Explanation:

The linear equation can be represented in a slope intercept form as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

Using the table let get 2 points

(2, 27)(3, 28)

let find the slope

m = 28 - 27 / 3 -2 = 1

let's find b using (2, 27)

27 = 2 + b

b = 25

Therefore,

y = x + 25

f(x) = x + 25
