To find the equation of the line that passes through the points \( (-2, 11) \) and \( (9, 22) \), we first need to calculate the slope \( m \). The slope \( m \) is given by: \[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{22 - 11}{9 - (-2)} = \frac{11}{11} = 1 \] Now that we have the slope, we can use the point-slope form \( y - y_1 = m(x - x_1) \) with one of the points. Using the point \( (-2, 11) \): \[ y - 11 = 1(x - (-2)) \\ y - 11 = x + 2 \\ y = x + 13 \] So, the equation of the line is: \[ y = 1x + 13 \] This means the final answer is: \[ y=1x+13 \]
