In this question we'll recall about the equation of the line y equal to the mx plus b.
00:07
In this formula here, the m stands from the slop equal to y2 minus 1 over x2 minus x1.
00:16
The b stands from the y intercept.
00:20
And now in this question here we're given the two point, minus 2, minus 2, and the 17.
00:27
Here we can identify this will be the x1x2 y2 so if we apply into the formula we can find the slot m equal to the 7 minus minus 2 over the 1 minus 2 and then we get equal to 9 over 3 or equal to 3.
00:52
When again the m here we plug into the formula to get the y ewe.
00:58
Equal to the 3x plus b.
01:01
To figure out the b here, we use this point now.
01:05
So means that y equal to minus 2, x equal to the minus 2 as well, plus b.
01:13
And doesn't implies that the minus 2 equal to the minus 6 plus b, or it means that the b equal to minus 2 plus 6 equal to 4...
