Answer:

m=2

Explanation:

We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.

Therefore, substituting the values of x=3 and y=-1 in the given line, we have,


y=mx-7


(-1)=m(3)-7


-1+7=3m


6=3m


m=2

Hence,the value of m will be equal to two.
