Intercept of a Line For any line y = ax + b, a is the slope b is the y-intercept Let’s look at y-intercept here Y-intercept (the number b) controls the where the line crosses the y-axis Now, When b = 0: line crosses y-axis from the origin When b > 0: line crosses y-axis from above the origin When b < 0: line crosses y-axis from the origin Let’s look at the graph ˚to understand how We observe that y = x crosses y-axis at Origin (0, 0) y = x + 1 crosses y-axis above the Origin (0, 1) y = x + 2 crosses y-axis above the Origin (0, 2) y = x – 3 crosses y-axis below the Origin (0, –3)
