4. Find the equation of the line that goes through the point (1,-1) and has a slope of 5.
frutty [35]

Answer: y=5x-6

(y-y_{1}) =m(x-x_{1})

plug in given values where m is slope and y1 and x1 are values

y-(-1)=5(x-1)

y+1=5(x-1)

y+1=5x-5

y=5x-6

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from table.</em>

Point (-1, -1)

Point (0, -5)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.  Rate of change and slope are identical.

  1. Substitute [SF]:                    m=\frac{-5+1}{0+1}
  2. Add:                                     m=\frac{-4}{1}
  3. Divide:                                 m=-4
