Question

Write an equation in slope-intercept form of the line.

The image is of a 2-dimensional graph with an x-axis and a y-axis. A line is passing through coordinates (4,1), (3,0), (0,-3) and (-1,-4).

Answer 1

y=x-3

Explanation:

To find slope, use m=y2-y1/x2-x1, using values of x and y from two different points. Once you have found slope, take another point and use the point-slope equation y-y1=m(x-x1) and substitute in slope for m and the point for x1 and y1. Isolate y by subtracting y1 from both sides.
