Hi, there--
.
If I interpret your question correctly, the numbers you provided are x-values and you need to find the y-values that go with them.
.
Ordered pairs (x,y) are the coordinates of points that make the equation true. So, we substitute the value we are given for x, and solve for y.
.
[1] Let x=0. Substitute 0 for x in the equation.
.
y=5x-6
y=5%280%29-6
y=0-6
y=-6
.
The equation y=-6 means that the ordered pair (x,y)=(0,-6) satisfies your equation.
.
.
[II] Let x=1. Substitute 1 for x in the equation.
.
y=5x-6
y=5%281%29-6
y=5-6
y=-1
.
The ordered pair (1,-1) satisfies your equation.
.
.
[III] Let x=2. Substitute 2 for x in the equation.
.
y=5x-6
y=5%282%29-6
y=10-6
y=4
.
The ordered pair (2,4) satisfies the equation.
.
There are two other ways to find points which satisfy an equation. One uses a table, the other the graph of the line for the equation.
.
