Y = -1/2 x + 2 Graph y = -2x + 3. Find the slope of -9x + 3y = 6. 3 Find the xintercept of 3x + 9y = 27 9 Find the yintercept of 4x – 5y = 10. -2 Find the x and yintercepts of -2x + 4y = 16 x int = -8 or (-8,0) y int = 4 or (0,4) Graph x + 2y = 4 using the x and yintercepts. Glazed doughnuts are $5 per box. Lemon are $6 per box. You need to raise $600. Write a linear model. 5x + 6y = 600 True or False. X = 3 is a vertical line. True True or False. Y = 4 is a vertical line. false Graph x = 1 Graph y = -1 Which line is a horizontal line? A) x = 2 B) y = 2 C) y = 2x +2 B) y = 2 What is the slopeintercept form of the line? Slope = 5 y-int= 8 Y = 5x + 8 Write the pointslope form. Slope = 4 Point (2,1) y – 1 = 4(x – 2) Write the slopeintercept form of the line containing (1, -3) and perpendicular to Y = -1/4 x + 7 Y = 4x - 7 Write the slope – intercept form of the line passing through (1, 4) and (2, 6). Y = 2x + 2 In 1980, a company made $6000. In 1990, the company made $36,000. A) Write a linear model. Let x = 0 represent 1980. B) Predict the profit in 2000. A) y = 3000x + 6000 B) $66, 000 X and y vary directly. Y = 24 when x = 6 Write an equation that relates the variables. Y = 4x X and y vary directly. Y = 18 when x = 2. Find y when x = 5 45 The graph of y = kx will: A) always have a positive slope B) be a horizontal line C) pass through (0,0) C) pass through (0,0) Does the table represent direct variation? If yes, give the equation. X 6 24 48 60 y 1 4 8 10 Yes Y = 1/6 x The area varies directly with the width. A= 20 when w = 4. A) Write the equation. B) Then find the area when the width is 10. A) A = 5w B) 50
