(0, 3); m = 18 y 3 = 18x y 3 = 18x y + 3 = 18x y + 3 = 18x 20 Write an equation for the line in point slope form through the points (2, 6) and ( 1, 8). 21 Use the point-slope form to write an equation of a line through the given points. ( 3, 2) and (3, 4) y 3 = x Suppose you are given a graph of a linear equation. ompare the methods you would use to find the equation of the line in slope-intercept form and in point-slope form. To find either equation, find the slope and y-intercept of the line as well as the coordinates of one point on the line. ll of these can be found from the graph. To find either equation, find the y-intercept of the line. For slope-intercept form, find the slope from the graph. For point-slope form, find the coordinates of one point on the line, which can also be read from the graph. To find either equation, find the coordinates of one point on the line. For slopeintercept form, find the y-intercept from the graph. For point-slope form, find the slope of the line. To find either equation, find the slope of the line. For slope-intercept form, find the y-intercept from the graph. For point-slope form, find the coordinates of one point on the line, which can also be read from the graph. opyright by Pearson Education Page 8 of 9

Substitute x = 1 into the equation and solve for x. Substitute y = 1 into the equation and solve for y. 24 an you graph a line if its slope is 0? Explain. Yes, the graph of a line with a slope of 0 is a horizontal line. Yes, the graph of a line with a slope of 0 is a vertical line. Yes, the graph of a line with a slope of 0 is a diagonal line. No, a slope of 0 does not exist, so the line cannot be graphed. 25 car company offers financing to its customers. For the newest model, customers can pay $2000 down and then $250 a month. Write an equation for this situation. What does the independent variable represent? What does the dependent variable represent? y = 250x ; the independent variable, x, represents the amount of money paid on the car and the dependent variable, y, represents the number of months after buying the car. y = 2000x + 250; the independent variable, x, represents the amount of money paid on the car and the dependent variable, y, represents the number of months after buying the car. y = 250x ; the independent variable, x, represents the number of months after buying the car and the dependent variable, y, represents the amount of money paid on the car. y = 2000x + 250; the independent variable, x, represents the number of months after buying the car and the dependent variable, y, represents the amount of money paid on the car. opyright by Pearson Education Page 9 of 9
