Okay, so you're given the equation y plus 1 is equal to 7 over 8 x, and you need to find x, y, and then the coordinate point x, comma, y, when x is negative 2, 0, 1, 8, 7th, and 2.
00:32
So first thing i recommend subtract one from both sides.
00:37
That way you have y equals 7 over 8x minus 1, and then you can just plug in values of x to get your value of y.
00:49
So 7 over 8 times negative 2, you're plugging in negative 2 for x.
00:59
And then subtract 1.
01:00
This is negative 2 .75.
01:09
So we did 7 over 8 times negative 2 minus 1.
01:19
So this is the point negative 2 comma negative 2 .75.
01:26
You have to have the parentheses.
01:28
It's part of the notation.
01:30
If we plug in x is equal to 0, that means this term is 0 and we just have minus 1...
