1 Slope-Intercept Form Practice True False Questions Indicate True or False for the following Statements.. The slope-intercept form of the linear equation makes it easier to graph because the starting point is always the y-intercept and the slope direct the steepness of the line. ( 2. Given that the line y 2 = x p and the line ax + = y are parallel, the value of a is 6. (. The equation of the line passing through (0,4) and parallel to the line x + y + = 0 is x + y 20 = 0. ( 4. The equation of a line perpendicular to the line x + 4y = 2 and passing through the point (, 2) is 4x 4y = 4. (. The equation of a line parallel to x + 8 2y = 0 and passing through the point (,2) is x 2y + = 0. ( 6. The slope and the y-intercept of the equation: y =.6x 24 is slope = 24 and y-intercept=.6. ( 7. Lines x = 2y and y + = 0 are perpendicular. ( 8. 2x + y + = 0 and 4x + 6y + 7 = 0 are perpendicular lines. ( 9. y = 2x + 4 is an example of an equation expressed in slope-intercept form. ( 0. Lines represented by the equations y = x x + and y = 2 are not parallel. (. If a line passing through the point (,) is parallel to the line y = 2x +, then its equation is x y =. ( 2. The slope-intercept form is y = mx + b, where m is the y-intercept and b is the slope. (. The equation of the line parallel to the line x +2y = 8 and passing through the point (0,) is x +6y 2 = 0. ( Multiple Choice Questions For each question, four alternative choices are given, of which only one is correct. You have to select the correct alternative and mark it in the appropriate option. 4. Consider the pattern: Point 0 = (0,4), Point = (,2), Point 2 = (2,0), Point = (,-2), Point 4 = (4,-4). If this pattern continues, what will be the coordinates of point 0? (0,-0) (0,-2) (0,-4) d.
