For each expression listed, is it a difference of squares? Explain yes or no and why or why not. Explain in enough detail so there is no doubt that it is or isn't a difference of squares. Examples were completed in class as well as in Worked Examples in D2L. 1. y5 − 25 2. 9m2n2 − 121 3. p18 − q10 4. 16r2 − 27

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
