To find the slope, you can use the formula:
. Start at where the graph intersects at the y-axis, which is -4. So, it rises up 2 units and goes left 3 units, which makes the slope
.
To find the y-intercept, you would start at where the graph intersects at the y-axis, which is -4 and this would be the y-intercept.
To find the equation, you can use the formula: y = mx + b. m is slope and b is the y-intercept. Plug the slope and y-intercept you found earlier. Thus, your final answer should be:
