# Some questions on slope and intercepts.

Complete each ordered pair so that it satisfies the given

equation.

1---- y = 2x + 5: (8, ), (-1, ), ( ,-1)

Use the given equations to find the missing coordinates in the

following tables.

2------

y= -x+4

X Y

-2

0

2

0

-2

3-------------Graph each equation. Plot at least five points for each equation.

x - 2y = 6

4--------------find the slope of each line.

5---------------

6---------------Graph the line with the given point and slope.

The line through (-2, 5) with slope -1

7---------------

Draw l1 through (-4, 0) and (0, 6). What is the slope of any

line parallel to l1? Draw l2 through the origin and parallel to l1.

8-----------------Write an equation for each line. Use slope-intercept form if

possible.

9------------

10-------------Find the slope and y-intercept for each line that has a slope

and y-intercept.

X+2y=3

11-----------

Y+4x=8

12----------determine whether the lines are parallel,

perpendicular, or neither.

Y=x+7

Y=-x+2

13------------Write each equation in slope-intercept form.

Y+3=-3(x-6)

14------------Find the equation of the line that goes through the given point

and has the given slope.

(-1, -5), -8

15-------¬Find the equation of each line. Write each answer in slope intercept

form.

(-2, 1).

16------------Find the equation of each line in the form y = mx + b if

possible.

The line through (3, 2) with undefined slope

17----------------Write a formula that expresses the relationship described by

each statement. Use k for the constant in each case.

m varies directly as p.

18------------ Write a formula that expresses the relationship described by

each statement. Use k for the constant in each case.

u varies inversely as n.

19-----------------Find the variation constant, and write a formula that expresses

the indicated variation.
