Use the equation (x2-x1)/(y2-y1)
Substitute the value of x and y
Slope =1.000/2.000=0.5
X-intercept=10/-1=-10.0
Y-intercept=10/2=5
H=3t+10 and h=-16t+15t+6
They will never be at the same height at the same time
(2^8 . 5^-5 . 19^0)^-2
using PEMDAS
this = (2^8 * 1/5^5 * 1)^-2
= (5^5 / 2^8)^2
= 5^10 / 2^16
