A line goes through the points (1, -19), (-4,1), (0, -15), (2, -23). What is the slope and y- intercept of the line

Step-by-step explanation:

The y-intercept is super easy. The y-intercept exists when x = 0; therefore, the point given where x = 0 is found in (0, -15). That means that the y-intercept is -15. Easy enough. Now, the slope.

Since all these points are on the same line, using any 2 of them in the slope formula will get us the slope. I picked the first 2 points (1, -19) and (-4, 1):

The y-intercept is -15 and the slope is -4

i think this could be a possible answer (1 / 84) -1

good luck! : d
