Question

What linear function equation has a line that goes through both (-1,4) and (3,2)

Answer 1

Answer:

The equation would be y = -1/2x + 7/2

Step-by-step explanation:

To find the equation, we first need to use the slope formula.

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

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

m = -2/4

m = -1/2

Now that we have that, we can use that and a point to find the full equation.

y - y1 = m(x - x1)

y - 2 = -1/2(x - 3)

y - 2 = -1/2x + 3/2

y = -1/2x + 7/2
