Answer:
y - intercept = 0
Slope of line = 2.86
Step-by-step explanation:
THE y-intercept is the point on the y - axis where the line crosses the y - axis. The y-intercept of the graph is 0.
The slope of the line is the ratio of change in the y-axis to the x - axis.
Gradient / slope = Δy / Δx = (y2 - y1) / (x2 - x1)
Drawing a right angle triangle at any point on to meet the line of best fit :
y2 = 35, y1 = 15, x2 = 12, x1 = 5
Slope = (y2 - y1) / (x2 - x1) = (35 - 15) / (12 - 5)
Slope = 20 / 7 = 2.857
Slope = 2.86
The area of a triangle with base 'b' and height 'h' is given by the formula:
It is given that the area of a triangle is .
It is given that the base of the triangle is 5 times the height.
So,
We have to determine the height of the triangle.
Since,
So,
So, h = 24 cm
Therefore, the height of the triangle is 24 cm.
Option 2 is the correct answer.
