Hello there! Given the equation of the line, we can identify our slope and y-intercept:
Slope: 12/1
y-intercept: -7
To identify the slope, we take the number that has a variable next to it and turn it into a fraction. Because the slope is 12, we can represent this as the fraction 12/1. The y-intercept always will be the initial value, or the number we add or subtract by that does not have a variable next to it. Hope this helps!
