Question

Write an equation in point slope form of the line that passes through the given points. (-1,4) and (1,2)

Answer 1

First you need to determine the slope. m= y2-y1\[m = y1-y2 \div x1-x2\]

Answer 2

Point-slope form is

\[y - y_0 = m(x-x_0)\]

Pick 1 point as (x0,y0) and calculate m as @nelsonjedi said above.

Answer 3

Recheck your slope.

Answer 4

The slope is -1 and the equation is y-4=-1(x+1).
