Sagot :
(-2,-6) and (2,-3) are points on the graph
Here, we want to select the ordered pairs that are on the graph
What we have to do here is to substitute the coordinates of the points into the equation
If we substitute say for example the x value, and we are able to get the y value, then the point is on the graph
We look at each of the points as follows;
a) (-9,-6)
[tex]3(-9)-4(-6)\text{ = -27+24 = -3}[/tex]This is not on the equation
b) (-2,-6)
[tex]3(-2)-4(-6)\text{ = 6+24 = 18}[/tex]This is a point on the graph
c) (0,6)
[tex]3(0)-4(6)\text{ = 0-24 = -24}[/tex]This is not on the graph
d) (2,-3)
[tex]3(2)\text{ -4(-3) = 6+12 = 18}[/tex]This is a point on the graph
e) (3,10)
[tex]3(3)-4(10)\text{ = 9-40 = -31}[/tex]This is not a point on the graph
