To find the x-intercept, plug 0 in for y:
0 = -x-1, so x = -1.
To find the y-intercept, plug zero in for x:
y=-0-1, so y = -1
The x-intercept is (0,-1) and the y-intercept is (-1,0)

It is linear. The highest power is 1 (x = x1, y = y1) so it is linear.
i think its pretty much the same thing because matrix X1 X2 IS ACTUALLY X1 X2
(y-y1)=(y2-y1/x2-x1)(x-x1)
The equation for the slope between the points A = (x1, y1) and B = (x2, y2) = (y2 - y1)/(x2 - x1), provided x1 is different from x2. If x1 and x2 are the same then the slope is not defined.
The slope between two points, (x1, y1) and (x2, y2) is: (y1 - y2) / (x1 - x2)
