Now that we have the value of k, we can substitute it into the equation y = kx to find y when x = 74:
y = -3 * 74
y = -222
Therefore, when x = 74, y = -222.
Yes, that is correct. When x = 74, substituting k = -3 into the equation y = kx gives us y = -3 * 74 = -222. Therefore, when x = 74, y = -222.
Correct! By substituting the value of k (which we have previously found) into the equation y = kx, we can calculate the value of y for a given x. In this case, when x = 74, y is equal to -222.
To find the value of y when x = 74, we need to substitute the value of x into the equation y = kx and solve for y.
In the given equation, y = kx, we already have the value of k, which is -3. To substitute x = 74 into the equation, we multiply -3 by 74:
y = -3 * 74
Calculating this expression gives us:
y = -222
Therefore, when x = 74, the value of y is -222.
