Math Problem Statement

Work out the gradient and the y-intercept of the line on the graph below. If your answer is a decimal, then round it to 1 d.p.

Solution

To calculate the gradient (slope) and the y-intercept of the line shown in the graph:

Steps:

  1. Gradient (Slope): The gradient (m) of a straight line is determined by the formula: m=change in ychange in x=ΔyΔxm = \frac{{\text{change in } y}}{{\text{change in } x}} = \frac{{\Delta y}}{{\Delta x}} From the graph, we need to find two points where the line intersects the grid. Using the coordinates of these points, we can calculate the change in y (vertical change) and the change in x (horizontal change).

  2. Y-Intercept: The y-intercept is the point where the line crosses the y-axis. From the graph, this can be directly read off as the value of y when x=0x = 0.

I'll analyze the graph and calculate the gradient and y-intercept for you. PIL import Image

However, to proceed with the calculations, I will need to visually identify two distinct points on the line (which will provide the change in y and x) and the y-intercept. Let me help you further by extracting and calculating these points. Could you give me a description of two easily identifiable points on the line (e.g., where it crosses grid points)? This will help in determining the gradient and the y-intercept more accurately.
