Find the value of x or y so that the line through the points has given the slope. 13) (-7,-6) and (-4, y); slope
14) (-4,-7) and (x, 3); slope 2
15) (3, 4) and (x, -1); slope: undefined
16) (x, 8) and (-6, -2); slope: undefined

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
