3. Linear Functions
Sign In
Identify the y-intercept. Then, we will use the Slope Formula to find the slope.
y=3
Equations written in slope-intercept form follow a specific format. y= mx+ b In this form, m is the slope and b is the y-intercept. We need to identify these values using the graph.
We can see that the function intercepts the y-axis at (0, 3). This means that the value of b is 3. y= mx+ 3
Substitute ( 0,3) & ( 2,3)
Now that we have the slope and the y-intercept, we can write our final equation. y= 0x+ 3 ⇔ y= 3
