Since the slope and a point are given, use the point-slope form of the line: y – y1 = m(x – x1) 35. Since the slope and a point are given, use the point-slope form of the line: y − y1 = m(x − x1 ) y − 1 = 2(x − (− 4)) 2 (x − 1) 3 3 y + 3 = −2(x − 1) y − (− 1) = − y −1 = 2x + 8 2 x − y = −9 3 y + 3 = −2 x + 2 2 x + 3 y = −1 37. Since we are given two points, (1, 3) and (– 1, 2), first find the slope. m= 3−2 1 = 1 − (− 1) 2 39. 9 y = −2 x + 3 2x + y = 3 Then with the slope and one of the points, (1, 3), we use the point-slope form of the line: y − y1 = m ( x − x1 ) 1 (x − 1) 2 2 y − 6 = x −1 y −3 = x − 2 y = −5 41.

The hypotenuse is 5 (the longest side). 9. Square the sides of the triangle. 4 2 = 16 5 2 = 25 6 2 = 36 The sum 16 + 25 = 41 ≠ 36, so the triangle is not a right triangle. 3. a = 10, b = 24 c2 = a2 +b2 c 2 = 10 2 + 24 2 = 100 + 576 = 676 c = 676 = 26 11. Square the sides of the triangle. 7 2 = 49 24 2 = 576 25 2 = 625 Since 49 + 576 = 625, the triangle is a right triangle. The hypotenuse is 25 (the longest side). 13. Square the sides of the triangle. 6 2 = 36 4 2 = 16 32 = 9 The sum 16 + 9 = 25 ≠ 36, the triangle is not a right triangle.

83. First we solve the equation ( x − 1) ( x − 2 ) ( x − 3 ) = 0 and use the solutions to separate the real number line. ( x − 1) ( x − 2 ) ( x − 3 ) = 0 x – 1 = 0 or x – 2 = 0 or x – 3 = 0 x = 1 or x = 2 or x=3 We separate the number line into the following 4 parts, choose a test number in each part, and evaluate the expression ( x − 1) ( x − 2 ) ( x − 3 ) at each test number. 1
