Slope-intercept form: y = mx + b
We know the slope, m, is 12. To find the y-intercept, b, we can take our given point, (3, 20), and plug in the x and y coordinates into the slope intercept form and solve.
y = 12x + b
20 = 12(3) + b
20 = 36 + b
-16 = b
Finally, we can plug in the slope and y-intercept to get our final equation in slope-intercept form.
y = 12x - 16
Hope this helps!! :)
