Find the equation of a line that passes the points (5, -9) and (0, -3)
kobusy [5.1K]

Answer:

y = -6/5x - 3

Step-by-step explanation:

Point Slope Form:  (y - y1) = m(x - x1)

<u>Step 1:  Find Slope</u>

m = \frac{y2-y1}{x2-x1}

m = \frac{-3 - (-9)}{0 - 5}

m = \frac{-3 + 9}{-5}

m = \frac{6}{-5}

m = \frac{-6}{5}

<u>Step 2:  Plug into Point Slope Form</u>

(y - (-3)) = -6/5(x - 0)

y + 3 - 3 = -6/5x - 3

y = -6/5x - 3

Answer:  y = -6/5x - 3

X &lt;-4 graphed as an inequality on a number line
iris [78.8K]
See it is < and not ≤ so we don't include -4

put a circle around -4  but don't shade it in
to get there, move 4 units left from 0


then we see x is less than -4
so shade to the left of the circle
