Question

Draw the graph of y = 2x + 4. Use the graph to find the area between the line and the axes.

Answer 1

Line on graph : 2 Mark
Formula for area : 1 Mark
Result : 1 Mark

When x= 0, y= 4,
When, $y=0,x=-2$

and when x= -1, y= 2

​

The triangle formed is a right-angled triangle with base 2 units and height 4 units.

Area enclosed = $\frac{1}{2}\times b\times h$
=$\frac{1}{2}\times 2\times 4$
=$4sq.units.$
