Final answer:

To write the equation of a line in slope-intercept form, we use the formula y = mx + b. Using the given slope and point, we can substitute these values and find the equation to be y = -4x + 2.


Step-by-step explanation:

To write the equation of a line in slope-intercept form, we use the formula y = mx + b, where m represents the slope and b represents the y-intercept. Since the slope is -4, and the line passes through the point (-3, 14), we can substitute these values into the formula.

Using the point (-3, 14), we have: 14 = -4(-3) + b.

Simplifying the equation, we get 14 = 12 + b. Subtracting 12 from both sides, we find that b = 2.

Therefore, the equation of the line in slope-intercept form is y = -4x + 2.
