Pis the center of two concentric circles. pq=4.2 and ps=8.2. rs is tangent to the smaller circle and a chord of the larger circle. what is the length of rs to the nearest tenth? a 8.1 b 14.1 c 16.4 d 12.2

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
