Question

Solve the system by graphingy= 4x + 3y= -x - 2

Answer 1

First equation (y= 4x + 3)

Let us find two points to plot the graph

x y

0 4(0) + 3 = 3 (Multiplying and adding)

1 4(1) + 3 = 7 (Multiplying and adding)

Plotting the graph, we have:

Second equation (y= -x - 2​)

Let us find two points to plot the graph

x y

0 -(0) - 2​ = -2 (Multiplying and adding)

1 -(1) - 2​ = -3 (Multiplying and adding)

Plotting the graph, we have:

Then we plot the both graphs:

We can see that the answers are x=-1 and y=-1, as they are the coordinates of the intersection point.
