graphing linear equations
vectored instruction
equation:
y = 11-3x
identify the
y-coordinate.
(5, ?)
assume this is a
point on the graph
of y = 11-3x

Explanation:

Step1: Substitute x = 5 into the equation

We have the equation \( y = 11 - 3x \). Substitute \( x = 5 \) into this equation.
\[ y = 11 - 3\times5 \]

Step2: Calculate the value of y

First, calculate \( 3\times5 = 15 \). Then, subtract this from 11:
\[ y = 11 - 15 = -4 \]

Answer:

-4
