13. Write an equation in slope-intercept form for the
line that has a slope of 12 and passes through the
point (3, 20).

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!! :)

i've never heard of it before.
