Question

The equation of a line is given below.

2x+y=-3
Find the slope and the y-intercept.
Then use them to graph the line.

Answer 1

-2 is slope and -3 in y-intercept

Explanation:

Starting with 2x + y = -3

Subtract 2x from both sides to get y alone:

y = -2x -3

This is now in slope-intercept form, which is y=mx+b, where m=slope and b=y-intercept.

-2 is in the m spot, so it is the slope

-3 is in the b spot, so it is the y-intercept

Answer 2

Slope = -4.000/2.000 = -2.000

y-intercept = -3/1 = -3.00000
