Write each equation in slope-intercept form of the equation of a line. underline the slope and circle the y-intercept in each equation. 3x+4y–12=0 2x+y=1

First equation:  3x+4y-12=0.  Solving for 4y, we get 4y = -3x + 12, from which

                                          y = (-3/4)x - 3.  The slope is -3/4 and the y-int. is -3.

Second equation:  2x + y = 1.  y = -2x + 1.  The slope is -2 and the y-int. is 1.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

1/800 is the right answer
