Question

graphing linear equations
vectored instruction
equation:
y = 2x - 1
identify the
y - coordinate.
(6, ?)
assume this is a
point on the graph
of y = 2x - 1.

Explanation:

Step1: Substitute x = 6 into the equation

We have the linear equation \( y = 2x - 1 \). To find the y - coordinate when \( x = 6 \), we substitute \( x = 6 \) into the equation. So we get \( y=2\times6 - 1 \).

Step2: Calculate the value of y

First, calculate \( 2\times6=12 \). Then, subtract 1 from 12: \( 12 - 1 = 11 \).

Answer:

11
