Question

Find the equation in slope-intercept form, of the line passing through the points (1,3) and (-1,2)

Answer 1

Answer:

The equation of the line would be y = .5x + 2.5

Step-by-step explanation:

In order to find this, we must first find the slope of the equation.

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

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

m = -1/-2

m = .5

Now that we have the slope, we can use either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 3 = .5(x - 1)

y - 3 = .5x - .5

y = .5x + 2.5
