Terni wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (2, 3). 4-(-2) 6 Step 1: =a = 3 =2 Step 2: d= 2(-2)+5 Step 3: d=-4+b 7=0 Step 4: = 2x47 Which best describes Terri's first error? 1 . Instep 1, the slope of the line should be 9. r 1 M ' In step 2, she should have substituted the point (4, 6). Oo 0 ' 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
