So in this problem, we are asked to find the equation of the line that passes through two points being negative 1, 4, and 2 .7.
00:15
Okay, so we will need to use point slope form, which is y minus y 1 equals m times x minus x1.
00:27
And we have already have y1 and x1, it can be either of these two points, but we need to find the slope.
00:35
So to find the slope, you'll use the slope formula, which is y2 minus y1 over x2 minus x1.
00:42
So plug in 7 minus 4 over 2 minus negative 1 to get that the slope equals 3 over 3, which simplifies to 1.
00:56
So there we have the slope.
00:58
M equals 1, and we have a pair of points that we can use...
