Final answer:
Yes, (-1,-4) is a solution to the equation y = 8x + 4.
Step-by-step explanation:
Yes, (-1,-4) is a solution to the equation y = 8x + 4. In order to determine if a point is a solution to an equation, we substitute the x and y values into the equation and check if the equation holds true. Let's substitute (-1,-4) into the equation:
y = 8x + 4
-4 = 8(-1) + 4
-4 = -8 + 4
-4 = -4
The equation holds true, therefore (-1,-4) is a solution to the equation.
