Slope intercept form is y equals mx plus b, meaning effectively if we are asked to put this equation in slope intercept form, they're asking us to solve this equation out for y.
00:13
We want to get y completely by itself.
00:16
So that's going to take multiple steps.
00:18
First step would be to move the 10x from the left side of the equation to the right side.
00:24
Instead of 10x being with that y term, we want 10x to be with the constant, the 70.
00:29
Well, the opposite of positive 10x, which is what we have here, is negative 10x.
00:35
The opposite of addition is subtraction, meaning to move 10x to the other side, we need to subtract it.
00:43
That would leave us with only negative 7y on the left side of the equation, so getting closer, not done, but getting closer to having y by itself.
00:52
And on the right side of the equation, we have negative 10x plus 70.
00:57
Yes, you could write that as 70 minus 10x, but remember, slope intersub form is y equals mx plus b.
01:07
The x term comes first, the constant term comes second.
01:10
So that's why i'm writing it in that form.
01:13
Now, all we have to do to get y by itself then is to get the negative 7 moved over to the other side as well...
