Q:
# What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3,1)?A. y=3x+1B. y=x-3C. y=2x+5D.y=2x-5

Accepted Solution

A:

The correct answer is D) y = 2x - 5To find the equation of the line, start by finding the slope. You can do this by using the slope formula below. m(slope) = (y2 - y1)/(x2 - x1)m = (1 - -3)/(3 - 1)m = 4/2m = 2Now that we have the slope, we can use it along with either point in point-slope form to get the equation. y - y1 = m(x - x1)y - 1 = 2(x - 3)y - 1 = 2x - 6y = 2x - 5
