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
2 answers:
Answer:
B. 1
Step-by-step explanation:
they only cross at one point... look below
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.
