Question

Solve the system of linear equations by graphing. y = –5/2x – 7 x + 2y = 4 What is the solution to the system of linear equations? A. (–4.5, 4.25) B. (–1.7, –2.8) C. (0, –7) D. (3, 0.5)

Answer 1

(–4.5, 4.25)

Step-by-step explanation

The first equation is

`y = - (5)/(2)x - 7`

This function is in the slope-intercept form

The second equation is:

x + 2y = 4

2y =-x+ 4

`y = - (1)/(2)x + 2`

The graph of the two functions are shown in the attachment.

The point of intersection represents the solution to the system of equations they represent.

The solution is

(–4.5, 4.25)
