It's a linear function. We need only two points to sketch the graph.
f(x) = -5x + 4 → y = -5x + 4
for x = 0 → y = -5(0) + 4 = 0 + 4 = 4 → (0, 4)
for x = 1 → y= -5(1) + 4 = -5 + 4 = -1 → (1, -1)
The domain and the range is the set of all real numbers.
(0,0) is the vortex for this problem

Answer:

Step-by-step explanation:
Slope
(2, 5) and (14, -4)
_______________
When we solve for slope within two points, we have to follow the formula of slope.

X and Y - The first and second number in both points
1 and 2 - The first or second number within one point
Substitute :


Simplify :

Yes, one pair of sides is both parallel and congruent
I think that's it
