Question

What is the gradient of the blue line

Answer 1

Answer:4

Step-by-step explanation:

When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line, 14 .

Answer 2

The gradient of the blue line given in the graph is 4 and this can be determined by using the slope intercept form and point slope form of the line.

Given :

The graph of the line is given.

The following steps can be used to determine the equation of a line given in the graph:

Step 1 - First determine the points through which the line passes through that is:

Points - (4,0) and (6,8)

Step 2 - Use the point-slope form of the line which is given by the

equation:

$\frac{y-y1}{x-x1} = \frac{y2-y1}{x2-x1}$

where $(x_{1},y_{1})$  and $(x_{2}, y_{2})$ are the point on the line.

Step 3 - Substitute the value of the points in the above equation.

$\frac{y-0}{x-4} = \frac{8-0}{6-4}$

Cross multiply in the above equation.

2y = 8(x - 4)

y = 4x - 16

Step 4 - Now, compare the above equation with slope-intercept form.

m = 4
