Question

Solve the following system of equations graphically. Select the graph that shows the correct solution of the system.

x + y = 2
x = 1

Answer 1

it should be the first graph

Answer 2

First one

Explanation:

rearrange x + y = 2 in the form y = mx + c

y = -1x + 2

means gradient is -1 and y-intercept is 2. such line is shown in the first graph

see where x = 1 and draw a straight line. Such line is also only shown in the first graph.
