The value of the function y = 18x - 13 when x = -4 can be found by substituting -4 into the equation:

y = 18(-4) - 13

y = -72 - 13

y = -85

Therefore, the value of the function is negative 85.

Apologies for the confusion. I made a mistake in my calculation.

To find the value of the function y = 18x - 13 when x = -4, we substitute -4 into the equation:

y = 18(-4) - 13

y = -72 - 13

y = -85

Therefore, the correct value of the function is -85.

To find the value of the function y=18x−13 when x=−4, substitute the value of x into the equation:

y = 18(-4) - 13

Now simplify the equation:

y = -72 - 13

Combine like terms:

y = -85

Therefore, the value of the function is -85.

To find the value of the function y=18x−13 when x=−4, we need to substitute the value of x into the equation and solve it.

Step 1: Plug in the value of x into the equation.
y = 18(-4) - 13

Step 2: Simplify the equation.
y = -72 - 13
y = -85

Therefore, the value of the function y=18x−13 when x=−4 is -85.
