First, let's calculate the slope of the line using the two given points.
slope = (y2 - y1) / (x2 - x1)
slope = (-1 - (-4)) / (1 - 0)
slope = (3) / (1)
slope = 3
Now that we have the slope, let's use the point-slope form of the equation of a line to find the equation in slope-intercept form.
y - y1 = m(x - x1)
y - (-4) = 3(x - 0)
y + 4 = 3x
Now, let's rewrite the equation in slope-intercept form by isolating y:
y = 3x - 4
Therefore, the equation of the line in slope-intercept form is y = 3x - 4.

Write the equation of the line in slope-intercept form.
We will first calculate the slope using the given points.
slope = (y2 - y1) / (x2 - x1)
slope = (-4 - 1) / (1 - 0)
slope = -5 / 1
slope = -5
Now that we have the slope, we will use the point-slope form of the equation of a line to find the equation in slope-intercept form.
y - y1 = m(x - x1)
y - 1 = -5(x - 0)
y - 1 = -5x
Now, we will rewrite the equation in slope-intercept form by isolating y:
y = -5x + 1
Therefore, the equation of the line in slope-intercept form is y = -5x + 1.
slope = (y2 - y1) / (x2 - x1)
slope = (-4 - 1) / (1 - 0)
slope = -5 / 1
slope = -5
Now that we have the slope, we will use the point-slope form of the equation of a line to find the equation in slope-intercept form.
y - y1 = m(x - x1)
y - 1 = -5(x - 0)
y - 1 = -5x
Now, we will rewrite the equation in slope-intercept form by isolating y:
y = -5x + 1
Therefore, the equation of the line in slope-intercept form is y = -5x + 1.
