If the line represented by the equation 3x + αy = 8 passes through the points (2,2), then the value of α is
1
4
3
0
3x + α y = 8
3(2) + α (2) = 8
6 + 2 α = 8
2 α = 2
α = 1
The line, represented by the equation 3x - 8y = 2, passes through the point (k,5), the value of k is:
Find the value of k, if the line represented by the equation 3x – ky = 12 passes through the point (4,2). [2 MARKS]
