We're being asked to write the equation of a line that contains, or that has an x intercept of 1 -0 and a y intercept of 0, 4.
00:08
Well, remember, slope intercept form is y equals mx plus b.
00:13
So to write this equation in this form, we need m, which is the slope, which we don't have, and we need b, which is the y intercept, which we do have, it's positive 4.
00:22
So we just have to find the slope.
00:24
To do this, we're going to use our slope formula, which remember is m equals y sub 2 minus y sub 1 divided by x sub 2 minus x sub 1.
00:33
So let's go back and label our ordered pairs.
00:36
So from the first order pair, 1 is our x sub 1, 0 is our y sub 1, and from the second ordered pair, 0 is our x 2 value, and 4 is our y sub 2 value...
