Answer:
m=2
Step-by-step 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,
⇒[tex]y=mx-7[/tex]
⇒[tex](-1)=m(3)-7[/tex]
⇒[tex]-1+7=3m[/tex]
⇒[tex]6=3m[/tex]
⇒[tex]m=2[/tex]
Hence,the value of m will be equal to two.
