We're given the equation y is equal to 5x minus 7, and we need to determine which of these points are on that line.
00:07
So what we do is we need to replace the x and the y and see which ones work.
00:11
So we have our x and our y value, x and our y value, x in our y value, x in our y value, x in our y value, x and our y value.
00:20
So we're going to try our first point.
00:22
So we have 8 equals 5 times x minus 7.
00:30
So our x value is 3.
00:33
So we get 8 is equal to 15 minus 7.
00:36
We get 8 is equal to 8.
00:39
So that works.
00:40
So this point lies on the line.
00:54
So we do the same thing for the second point.
00:56
We have negative 17 equals 5 times x minus 7...
