The graph of a line passes through two given points, as shown on the graph below. what is the equation of the line
written in general form?
x-y+5=0
x+y-5=0
x-y-5=0

The reflexive property of congruence lets you say that ∠pqr ≅

How can you tell when x and y are not directly proportional?

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
