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.
