Question

What value of b will make the point {3,-1} lie on the line y=mx-7 in standard {x,y} coordinate plane?

Answer 1

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,

⇒$y=mx-7$

⇒$(-1)=m(3)-7$

⇒$-1+7=3m$

⇒$6=3m$

⇒$m=2$

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