Posted on Updated on

dealing with finding an equation of a line.

 1 what is the standard form of the equation of this line? Choose one: 2x + y = 5 2x + y = 11 2x + y = 1
 2 What is the equation of this line? Choose one: y – 5 = -1(x – 3) y = 3 x = 3
 3 What is the equation of this line? Choose one: y + 3 = 0 (x – 4) y = -4 y = 4
 4 What is the Standard Form of the equation of a straight line for this graph? Choose one: 2x + 3y = 15 2x – 3y = 15 3x – 2y = 10
 5 find an equation in standard form of the line that passes through the points (1, -4) and (3, 2)? Choose one: x – y = 5 2x – y = 4 3x – y = 7
 6 find an equation in standard form of the line: – parallel to the line y = -3x + 1 and passing through the point (-1, 2)? Choose one: 3x + y = -1 3x + y = -5 3x + y = 1
 7 find an equation in standard form of the line: – perpendicular to the line y = -(¼)x + 5 and – passing through the point (-6, 4)? Choose one: 4x – y = 28 4x + y = 28 4x – y = -28
 8 The slope-intercept form of the equation of a straight line is y = – (2/3)x + 7/3. What is the standard form of the equation? Choose one: 2x – 3y = 7 2x + 3y = 7 2x – 3y = -7
