Answer: m = 3\frac{1}{2}

Step-by-step explanation:

the value of 7m−3 is half as big as the value of 12m+1 implies that

7m - 3 = \frac{1}{2} ( 12m + 1)

cross multiplying, we have

2(7m-3) = 12m + 1

Expanding the L.H.S , we have

14m - 6 = 12m + 1

collecting the like terms ,we have

14m - 12m = 1 + 6

2m = 7

Dividing through by 2

m = 7/2

m = 3\frac{1}{2}

So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.

So question 1 would be true because when you substitute the numbers in it equals the y value.

Question 2 is (4, -7)

Question 3 is False

Question 4 is true

Question 5 is true

See if you can do the rest!
