[Free] Write an equation in slope-intercept form for each table below. Show how you found the slope and y-intercept. Table (1): | x | 0 | 1 | 2 | 3 | 4 | |---|---|---|---|---|---| | y | 0 | 2.5 | 5 | 7.5 | 10 | Steps to find the slope (m) and y-intercept (b): 1. Calculate the slope (m) using two points from the table: \( m = \frac{y_2 - y_1}{x_2 - x_1} \) Let's use the points (0, 0) and (1, 2.5): \( m = \frac{2.5 - 0}{1 - 0} = 2.5 \) 2. Determine the y-intercept (b) by identifying the y-value when x = 0: The y-intercept is 0. Equation in slope-intercept form: \[ y = 2.5x + 0 \] Or simply: \[ y = 2.5x \]
