Standard Form

1. Given the following information, write the equation of each line in the y = mx + b (slope = m and y-intercept = b) form.

a)      S (2, 6) B (4, 3)

b)      J (-3, 8) A ( -2, 4)

c)      y-int. is -6 & slope is 4

d)      x-int. is -12 and y-int. is 6

e)      slope is & C (16, 7)

f)        H (-3, 10) and y-int. is -2

g)      C (7, 8) S (3, 10)

2. Find the equations of the following lines given the information.

Put in slope y-intercept form.

a)      A (1,2), B(3,8)

b)      b) D (4, -3) and slope is 5

c)      x-int is -3 and Q( -2, 6)

d)      y-int is 4 and S (3, -5)

3. Find the equation of the following lines in Standard Form.

         a) Slope = -3 and y-int is 2          b) Slope = 4 and passes through (-3, 4)

         c) Passes through (3,1) (6,-2)    d) Passes through (-4,-6) (8, 10)

e) m = 2 and x-int of 2/3    f) x-int = -4/3 and y-int = -2/3

g) (-2, 5) and x-int of -1/2

4. Find the equation, in STANDARD FORM of the following graphs.

5. A line passes through the point (2, 3) and has y-intercept -3. Find the x-intercept. (Do not graph). This is a trickier one!
