Today, you will be able to: Put equations into slope-intercept form SLOPE-INTERCEPT FORM OF A LINE: y = mx + b Put the following equations into slope-intercept form: y = 5 + 3x y = 3x + 5 y = -2 + 8x y = 8x - 2 y = 7 - 2x y = -2x + 7 y = 6 - 4x y = -4x + 6 y = 4 + 9x y = 9x + 4 y = 10 - 3x y = -3x + 10 Sometimes, to put an equation in slope-intercept form, we may have to get y alone! y + x = 4 -x -x y = x + 4 y - x = -2 +x +x y = x - 2 9. y + x = 7 -x -x y = -x + 7 10. y + x = -1 -x -x y = -x -1 11. y - 4x = 2 +4x +4x y = 4x + 2 12. y - 3x = 5 +3x +3x y = 3x + 5 13. y - 5x = 8 +5x +5x y = 5x + 8 14. y - 1/2x = 10 +1/2x +1/2x y = 1/2x + 10 15. x + y = 5 -x -x y = -x + 5 16. 3x + y = 6 -3x -3x y = -3x + 6 Problem 6: If f(x) = 8x - 1, evaluate f(3). f(3) = 8(3) - 1 = 23 Problem 7: If f(x) = -x + 10, evaluate f(-2). f(-2) = -(-2) + 10 = 12 Problem 8: If f(x) = 1/2x, evaluate f(18). f(18) = 1/2(18) = 9 Problem 9: If f(x) = 1/3x - 7, evaluate f(-12). f(-12) = 1/3(-12) - 7 = -11 Problem 10: If f(x) = -2/3x + 11, evaluate f(-6). f(-6) = -2/3(-6) + 11 = 15 Problem 11: If f(x) = -3/4x + 10, evaluate f(-8). f(-8) = -3/4(-8) + 10 = 16
