# Slope and Equation of a Line

Use the siders to change the slope (m) and y-intercept (b) to anaylze the relationship between direction of the line and equation of the line in slope-intercept form. Afterwards, answer the questions below using the graph and verfiy algebraically.

## Question #1

Write the equation of a line that has a slope of -2 and passes through the point (3,2). Show graphically and algebraically.

## Question #2

What is the equation of a line that is parallel to y=-2x+1 and through the point (1,2). Show graphically and algebraically.

## Question #3

Write the equation of a line that is perpendicular to y=4x+5 and through the point (2,3). Show graphically and algebraically.
