Answer:
y-intercept: 3
slope: -3
Step-by-step explanation:
The y-intercept is the point at which a line crosses the y-axis, which means that the y-intercept must be (0, y). The only value at which x is 0 is (0, 3), so the y-intercept is 3.
The definition of slope is rise over run, or:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Choose any two coordinates and replace the values in:
[tex]m=\frac{6-3}{-1-0} \\m=\frac{3}{-1}\\m=-3[/tex]
