To find the equation of the line in slope-intercept form (y = mx + b), we need to determine the slope (m) and the y-intercept (b).
-
Calculate the slope (m): Use the points (0, 1) and (1, -4). \[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 - 1}{1 - 0} = \frac{-5}{1} = -5 \]
-
Use the slope and a point to find b: We can use the point (0, 1) to find the y-intercept (b): \[ y = mx + b \implies 1 = -5(0) + b \implies b = 1 \]
-
Write the equation: Substitute the values of m and b into the slope-intercept form: \[ y = -5x + 1 \]
Thus, the equation of the line in slope-intercept form is: \[ y = -5x + 1 \]
The correct response is: y = −5x + 1
