Answer:

The graph in the attached figure

Explanation:

we have


y=2x+1 ----> equation A

The equation represent a linear equation (line) in slope intercept form

The slope is positive and is equal to
m=2

The y-intercept is the point (0,1)

The x-intercept is the point (-1/2,0)


y=-4x+7 ----> equation B

The equation represent a linear equation (line) in slope intercept form

The slope is negative and is equal to
m=-4

The y-intercept is the point (0,7)

The x-intercept is the point (7/4,0)

Remember that the solution of the system of equations is the intersection point both lines

To find out the intersection point, plot the intercepts, connect them to graph the line and identify the solution

using a graphing tool

The solution is the point (1,3)
