M1551 TEST 1 Preview sheet. When a number is underlined, it means you should be prepared to do similar problems with any number in place of the underlined number. Inequalities 1. Express “the distance from x to a ” as a mathematical function. 2. Solve the inequality | 5 x – 7 | > 10 . 3. Graph the functions y = | 5 x – 7 | and y = 10 , and use your picture to solve problem 1) graphically. Linear functions and equations 1. Write the equation of the line through (1 , 3 ) and (22 , 65 ) in the form y = mx + b . 2. Find the number a so that the “line through (5 , 3 ) and ( a , a )” has y -intercept (0 , -1 ). 3. Find both the slope and intercept of the line in problem 3 as a function of a . 4. Let f be a function and let p and q be numbers. Find both the slope and intercept of the “line through ( p , q ) and ( a , f ( a ))” as a function of a , p and q . Average rate of change 1. A particle moves along a number line so that its position at time t is f ( t ). What is its “average velocity of the particle on the interval from time
