Question

What is the equation of this line?

y= 2x - 3

y= -1/2x- 3

y= -2x - 3

y= 1/2x - 3​

Answer 1

First option) y= 2x - 3

Explanation:

[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.

[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.

-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.

[] Our equation is y = 2x - 3
