PLEASE HELP I'M BEING TIMED
Terri wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (–2, 3).
Step 1: m = StartFraction 4 minus (negative 2) Over 6 minus 3 EndFraction = StartFraction 6 Over 3 EndFraction = 2
Step 2: 3 = 2 (negative 2) + b
Step 3: 3 = negative 4 + b. 7 = b.
Step 4: y = 2 x + 7
Which best describes Terri’s first error?
In step 1, the slope of the line should be One-half.
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.
