Answer: 3, 2, 4, 3, 2, 1.
Step by Step Explanation:
These are the 3 equations of a line:
Ax + By = C: Standard form.
y = mx + b: Slope-intercept form.
y - y1 = m(x - x1).
We can see that all of the equations are simply the forms above with numbers plugged in. Equation 3 is not in any of the forms as it is in the form x = my + b, rather than the correct form y = mx + b.
Hope this helps.
