To find the equation of the line in slope-intercept form (y = mx + b), we first need to calculate the slope of the line.
The slope (m) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Using the points provided: (0, -4) and (1, -1)
m = (-1 - (-4)) / (1 - 0)
m = (3) / (1)
m = 3
Now that we have the slope (m = 3), we can use one of the points given to solve for the y-intercept (b). Let's use the point (0, -4).
-4 = 3(0) + b
-4 = 0 + b
b = -4
Therefore, the equation of the line in slope-intercept form is:
y = 3x - 4
The correct answer is option B: y = 3x - 4
