Use the image to answer the question.

An illustration of a coordinate plane with four quadrants shows the x-axis ranging from negative 9 to 9 and the y-axis ranging from negative 11 to 11 in increments of 1. A solid downward line with arrows at both ends is plotted on the graph. The line passes through the plotted points left parenthesis 0 comma 1 right parenthesis and left parenthesis 1 comma negative 4 right parenthesis.

To find the equation of the line in slope-intercept form (y = mx + b), we first need to determine the slope (m) and the y-intercept (b).

Finding the slope (m): The slope can be calculated using the formula: \[ m = \frac{y_2 - y_1}{x_2 - x_1} \] Given the points (0, 1) and (1, -4):
- \( (x_1, y_1) = (0, 1) \)
- \( (x_2, y_2) = (1, -4) \)
Plugging in the values: \[ m = \frac{-4 - 1}{1 - 0} = \frac{-5}{1} = -5 \]
Finding the y-intercept (b): We can use one of the points to solve for b. Using the point (0, 1): \[ y = mx + b \implies 1 = -5(0) + b \implies 1 = b \]

Now we have both the slope and the y-intercept:

Slope \( m = -5 \)
y-intercept \( b = 1 \)

Putting it all together, the equation in slope-intercept form is: \[ y = -5x + 1 \]

The correct response is: y = −5x + 1
