Tell whether the sequence is arithmetic or geometric. then graph the sequence.

1. 9, -18, 36, -72

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

To solve the system of equations below, pedro isolated the variable y in the first equation and then substituted it into the second equation. what was the resulting equation? { 5y=10x {x^2+y^2=36

If a line is defined by the equation y = 5x + 2, what is the slope?
