How many solutions will the following system of linear equations have? –2x + 4y = –7 y= -1/2x + 5 a. 0 b. 1 c. 2 d. infinite

ANSWER

B. 1

EXPLANATION

The given system of equations is;

–2x + 4y = –7

y= -1/2x + 5

We rewrite the first equation is slope intercept form:

4y = 2x–7

The two equations have different slopes.

This means that they will intersect at one point in the XY plane.

Hence the system has a unique solution.
