Can someone help me graph this and solve the problem thank you
Marizza181 [45]
Y - 3 = -1/4(x - 4)
y - 3 = -1/4x + 1
y = -1/4x + 1 + 3
y = -1/4x + 4

ok....the y int is (0,4)....the slope is -1/4...
       x int can be found by subbing in 0 for y and solving for x
       y = -1/4x + 4
       0 = -1/4x + 4
       1/4x = 4
       x = 4 * 4
       x = 16....so ur x int is (16,0)

so first plot ur points (0,4)....and since ur slope is -1/4, go down 1 space and to the right 4 spaces, then down 1, and to the right 4....keep doing this and u will cross the x axis at (16,0)
