Question 17 • Algebra 1

Alejandro made an error in the steps when determining the equation of the line that is perpendicular to the line 4⁢x−3⁢y=−8 and passes through the point (3,−2). Step Alejandro's Work 1 The equation written in slope-intercept form is y is equal to 4 thirds x plus 8 thirds , which has a slope of 4 thirds 2 The slope of the line perpendicular to the given line is negative 4 thirds 3 Substituting the point and the new slope into point-slope form results in y minus negative 2 is equal to negative 4 thirds times open paren x minus 3 close paren 4 Simplifying, the equation of the line is y plus 2 is equal to negative 4 thirds times open paren x minus 3 close paren Alejandro made his first error in which step?
