Cassidy wrote the linear equation y=5x+4. Then, she wrote the equation of the line that is parallel to y=5x+4 and that passes through (8,–2). If her new equation is in the form y=5x+b, what is the value of b?
Since it's parallel the scale is kept and you just plug in the point in order to get the y-intercept. [tex]y=5x+b[/tex] [tex](-2) =5 (8) + b[/tex] [tex]-2 =40 +b[/tex] [tex]b = -42[/tex]
