Solve the problem. Write all linear equations in slope-intercept form. A driver wants to gauge the fuel efficiency of her vehicle at speeds of 30 mph and above. She notices that traveling at an average speed of 45 mph
results in a rating of 40 mpg, whereas at an average speed of 50 mph, her car rates 30 mpg. Find a linear equation to model the gas mileage y for an
average speed of x mph. Find the slope-intercept form of the equation of the line.

Stefano accidentally dropped his sunglasses off the edge of a canyon as he was looking down. the height, h(t), in meters (as it relates to sea level), of the sunglasses after t seconds, is shown in the table. during its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber? 166 meters 176 meters 230 meters 240 meters its b.176 i took the test 166 is wrong and 176 is correct
