Question

Write an equation for each line in slope intercept form.
Slope = ½ and the y-intercept is (0,6)

Rewrite the equations In slope intercept form. Graph each line.

-4x + 6y =18


3y + x = 5

Write an equation for each line in point-slope form Slope =5, through (1,-1)

through (2,3) and (3, 5)

Answer 1

slope intercept form for the equation of the line
y = m x + b where m is the slope and b is the intercept for the point (x, y)

Answer 2

y-intercept is (0,6) b = value of y when x = 0 = 6
y = 1/2(x) + 6

Answer 3

Rewrite the equations In slope intercept form
write in the form y =
remember to keep the balance of the equation

Answer 4

Graph each line.
you only need 2 points to graph a line. the easiest to use are when y = 0 and when x = 0

Answer 5

point-slope form
y - y1 = m ( x - x1) where m is the slope and the points are (x1,y1) and (x, y)

Answer 6

y-6 =1/2(x -0)

y=1/2x -6.5 would this be right?

Answer 7

y=1/2x + 6

Answer 8

as posted above

Answer 9

Oh okay, thanks a lot!

Answer 10

read through all the post and let me know if you need more. do you want to post a sketch of the graph etc

Answer 11

That would be helpful, if you don't mind. : D
