Question

Solve the following system of equations by graphing.

y = -x-1
y = 14x - 4
A) (-4,3)
B) (-3,4)
C) (4,-3)
D) (3,4)

Answer 1

(0.2, -1.2)

Explanation:

When solving a system of equations by graphing, we first plot the two equations on a graph, then the point of intersection of the two graphs is the solution to the system of equations.

Therefore giving the equations y = - x - 1; and y = 14x - 4, we have to first plot the both linear equations using online geogebra graphing tool. The intersection of both linear graphs is the solution to the problem.

We can see that the point of intersection is A(0.2, -1.2)
