# Determining Slope And Intercept of A Line

Find the slope and y intercept of the line. Graph the line 7x-5y=35

Decide whether the given linear equations are parallel, perpendicular or neither. y=4x+9 y=-1/4x+5/4

Decide whether the given linear equations are parallel, perpendicular or neither. y=5x-7 y=5x+2

Write the standard from of the equation and the general form of the equation of the circle with radius r and center (h,k) then graph the circle r=10 (h,k)= (6,8)

#### Solution Preview

1. 7x-5y=35 so 5y=7x-35, y=1.4x-7, so slope = 1.4 and intercept = -7

2. since slope of y=4x+9 is 4 and slope of y=-1/4x+5/4 is ...

#### Solution Summary

The solution gives detailed steps on determining the slope and intercept for the given line. Also, the relationships (parallel, perpendicular or neither) between two lines are explained using the slope method. Finally, the procedure writting the standard form of a circle is shown if the radius and center are both given.
