WebDec 27, 2024 · From the graph, we can see that the intercept on the y axis is 4 while the intercept on the x-axis is approximately 1.33 or simply 4/3. This means, at x = 0, y = 4 and at y = 0, x = 4/3. Therefore the linear equation is; y = -3x + 4. However, the shaded area is below the line and so the operation will be with the sign less than(<). Also, we see ... WebIn this video we'll draw the graph for y = 3x. You may also see this written as f(x) = 3x.
