Find the value of x and y so that the line through the pair of points has the given slope.
Problem 1 :
(x, 3) and (5, 9) and slope (m) = 2
Problem 2 :
(-2, 3) and (4, y) and slope (m) = -3
Problem 3 :
(-3, -5) and (4, y) and slope (m) = 3
Problem 4 :
(-8, -2) and (x, 2) and slope (m) = 1/2
1) x = -7
2) y = -15
3) y = 16
4) x = 0
Problem 1 :
In the xy plane, the lines
y = mx - 7 are 2x + 3y = 6
are parallel. What is the value of m ?
Problem 2 :
A line passes through the points (-1, 2) and (5, b) and is parallel to the graph of the equation 4x - 2y = 13. What is the value of b ?
Problem 2 :
In the xy - plane above, line l is parallel to line m. What is the value of b?
Problem 4 :
In the xy-plane above, if line l is perpendicular to line t, what is the value of a?
1) m = -2/3
2) b = 14
3) b = 3/2
4) a = 10
Problem 1 :
The graph of the line in the xy plane passes through points (0, 0) and (1, 2). The graph of the second line passes through points (1, 2) and (k, 0). If the two lines are perpendicular, what is the value of k ?
Solution
Problem 2 :
The graph of the function f contains the points (0, 3), (-2, 7) and (5, k). If the graph of f is a line. What must be the value of k ?
(a) -13 (b) -7 (c) 5 (d) 8
1) k = 2
2) k = -7
