Answer:
c ≤ -9
Step-by-step explanation:
c / -3 ≥ 3
c ≤ -9
Remember, we flip the sign of the inequality by multiplying / dividing by a negative number.
Knowing that slope-intercept form is y=mx+b. mx being the slope and b being the y-intercept.
First, you will first find the slope, which is (y2-y1)/(x2-x1):
5-(-1) / 1-(-1) = Which becomes 6/2.
6/2 = 3. So the slope is 3x
Now when you plot the dots on a graph with a slope of 3 (basically 3/1 knowing that slope is rise over run) you will see that the point that intercepts on the y-axis is 2. So your y-intercept, or b in this equation, is 2.
I believe the slope-intercept form: y=3x+2
Yes because have the positive sign +
Since ABCD is parallelogram these rules apply:
Since
this implies that 
The answer is D.
Hope this helps.
