Chapter 9.5, Problem 38AYU

Students have asked these similar questions

type y = 1x + 1 into a graph. Where does this line cross the y-axis? Notice that these two lines are now parallel (they run in the same direction without ever crossing). Think about the only change you made, and write the equation of another graph in the form y = mx + b that would also be parallel to these two lines?

Write the equation of the line in standard form for problems 1 and 2. 1. y= 6/13x-2 2. y-3=2/3(x+6)

Problem #1 Convert the following equation from standard form to slope intercept form. 100x + 5y = 25 tep 1: Subtract or add the erm with the variable x to er from both sides of the quation tep 2: Divide the oefficient multiplied by he variable y on both sides of the equation Step 3: Write your equation in slone intercent form
