Question

kmarks Solve the following system of equations graphically on the set of axes below 1 y 22 - 4 y = -X – 7 Plot two lines by clicking the graph. Click a line to delete il. y 10 9 8 7 6 5 4 3 2. 1 5 6 7 8 9 10

Answer 1

Explanation:

For the first line :

1. Draw a line which has a slope of 1 /2

2. Adjust the line so that it has a y-intercept of -4.

For the second line:

1. Draw a line which has a slope of -1

2. Adjust this line so that it has a y-intercept of -7.

Finally, find the point where the two lines intersect.

The coordinates of the point of intersection are the solution to our system.

To get a line which has a slope 1/2, you start from (0, -4 ) and then move 2 units to the right and then 1 unit up.
