Answer:
-3.5 ( or -7/2)
Step-by-step explanation:
we can substitute the point into this function to find out the answer
that is:
4 = m*(-2) -3
7 = m*(-2)
m = 7 / (-2)
m = -3.5
The solution of a system of equations is the point at which the two lines intersect. Since y is already isolated, we can set the equations equal to each other by doing:
4x=4x+1
Subtract 4x from both sides
0=1
Since 0 cannot equal 1 in any case, the lines never intersect. There is no solution to the problem.
