Terri wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (–2, 3).


Which best describes Terri’s first error?

In step 1, the slope of the line should be 1/2.

In step 2, she should have substituted the point (4, 6).

In step 3, she should have subtracted 4 from both sides of the equation.

In step 4, the m and b values should be switched.
