Question

Find the slope and y-intercept of the line : x+y+3=0​

Answer 1

Step-by-step explanation:

y=mx+c⟶(i)

x−y+3=0.

⇒y=x+3⟶(ii)

Hence, slope of line, x−y+3=0 is 1.

Using the Slope Equation

Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
