Question

Find slope and y-intercept form​

Answer 1

Slope; -1

y-intercept: (0, 3)

Explanation:

The y-intercept is the point at which the line crosses the y-axis. Start at the origin (0, 0) and count the number of squares up to the y-intercept: 3.

So the y-intercept is (0, 3).

Again starting from the origin (0, 0), count the number of squares to the x-intercept, which is where the line crosses the x-axis. Again, that number is 3.

Thus, the slope of this line is m = rise / run = -3 / 3 = -1. A quick glance at the graph shows that y decreases as x increases, which confirms that the slope is negative.
