Question

Use the table to answer the question. X y -21-1 -1 -1 1 0 3 1 5 2 7 Which equation represents the relationship between x and y shown in the table? 1 O A. y = fx- -1 O B. y = x+3 Oc. C. y=2x-1 D. y = 2x + 3​

Answer 1

D. y = 2x + 3​

Explanation:

Use the table to answer the question.

x:-2 -1 0 1 2

y: -1 1 3 5 7

Which equation represents the relationship between x and y shown in the table.

Solution:

The table shows a linear relationship between x and y.

A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.

The table (x, y) has the points (-2, -1) and (0, 3). The equation is given by:

`y-y_1=(y_2-y_1)/(x_2-x_1) (x-x_1)\\\\y-(-1)= (3-(-1))/(0-(-2)) (x-(-2))\\\\y+1=2(x+2)\\\\y+1=2x+4\\\\y=2x+3`
