Write the equation of the line through the points (2,4)(-3,-1). write answer in a point slope form

luda_lava [24]

Answer:

The point-slope form would be y - 4 = x - 2

Step-by-step explanation:

In order to find the equation of the line, we first need to find the slope. For that, we use the slope formula.

m (slope) = (y1 - y2)/(x1 - x2)

Now we plug the numbers into the equation.

m (slope) = (y1 - y2)/(x1 - x2)

m (slope) = (4 - -1)/(2 - -3)

m (slope) = 5/5

m (slope) = 1

Now we can use point-slope form along with the slope and either point to write the equation.

y - y1 = m(x - x1)

y - 4 = (x - 2)

This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
