1. The variables x and y are related by the equation y = p𝑥 2 + qx, where p and q are constants. A
straight line is obtained by plotting
𝑦
𝑥
against x. If the points (1,9) and (5, 29) lies on the straight
line, find the values of p and q.
2. The non-linear equation y= a𝑥 2 + bx can be reduced to the linear form and the graph is
plotted as shown.
Find the values a and b.
3. A student wants to reduce a non-linear relation y = a𝑏 𝑥+1 into a linear relation by taking
logarithm to the base 10 and plotting a linear graph.
(a) If the vertical axis of the graph represents 𝑙𝑜𝑔10 y, state the representation of the horizontal
axis.
(b) If the intercept of the vertical axis is 2, find the value of a.
4. The variables x and y are related by the equation y = 3x (5-x).
𝑦
A straight line graph is obtained by plotting 𝑥 against x, as shown in the diagram.
Find the values a and b.
5. The variables x and y are related by the equation y = 103𝑥−2 .
Find the values of h and k.
