Question

Write an equation of the line in point-slope form that passes through the given points.

(3,5) and (4,7)

Answer 1

Answer: y=2x - 1

Explanation:

The point slope form equation is y=mx + b

m is the slope, to find slope we need to find the rise/run

We see that the y increase by 2 and x increase by 1, so the slope is 2.

The y-intercept is at (0,-1), so the b is -1

So we have the equation y=2x - 1
