Answer:
B) y = 3
Step-by-step explanation:
x = -1 is a vertical line. We want a line that is perpendicular, so it must be a horizontal line. Horizontal lines are in the form y=
The point it goes through is (2,3) so it goes through the y coordinate y=3
Therefore the line must be y=3
The brick will fall to the ground after 9 secs.
<h3>What are quadratic equations?</h3>
Given the equation for height as a function of time is h(t) = -16t2 + 1,296
The height of the brick on the ground is h(t) = 0. Substitute h(t) = 0 into the equation as shown:
Subtract 1296 from both sides
-16t² + 1,296 - 1296 = 0 - 1296
16t² = 1296
t² = 1296/16
t² = 81
t = 9secs
Hence the brick will fall to the ground after 9 secs.

Answer:
y=1/3x-5
Step-by-step explanation:
y=1/3x+b
0=1/3(15)b
0= 5+b
b=-5
