Directions: Using digits 1-9, write an equation of a line in standard form with given x- and y-intercepts. Each number can only be used at most once.
Hint
What numbers can we rule out as coefficients for x and y in the equation?
Answer
Possible answer:
9x + 2y = 36
x-intercept: (4,0)
y-intercept: (0,18)
9x + 2y = 36
x-intercept: (4,0)
y-intercept: (0,18)

8x + 4y = 64
y=-2x+16
x-intercept: ( 8,0) . value of x where y=0
y-intercept: (0,16 ) from y=mx+b format
6x+2y=12
x-int – (6,0)
y-int – (0,2)
