form to slope-intercept form.
If necessary, tell students how to find the
Observations
for this section.
Observation
Students use algebra to write 3x+4y=8 in y=mx+b form.
Answers may vary, especially the step order. One possible
answer:
Step 1
: Subtract 3x from both sides of the equation.
3x - 3x + 4y = 8 - 3x
Step 2
: Simplify the equation.
4y =
M
3x + 8
Step 3
: Divide both sides of the equation by 4.
4y

=
M

Step 4
: Simplify to get the answer.
y =
