Question

Work out the gradient of the line on the graph below. Give any decimal answers to 1 d.p. y 50 45- 40- 35 30- 25- 20- 15- 10- 5- O 5 10 ​

Answer 1

The gradient or slope of the line on the attached graph is 7.

The gradient or slope refers to the constant of proportionality or ratio between the variables y and x.

The gradient (or slope) of a line on a graph can be calculated using the formula:

Gradient = Change in Y/Change in X​ = (y₂ - y₁)/(x₂ - x₁)

The graph's line starts at the origin (0,0) and extends through the point (5, 35). We can calculate the gradient as follows:

=
`(35 - 0)/(5 - 0)` =
`(35)/(5)` = 7

Thus, we can conclude that the gradient is 7.
