Question

graph the equation using slope and y intercept.
x+4y=16

Answer 1

do you know how to find the slope and y intercept ?

Answer 2

4y=x+16
y=1/4x+4
1/4 is the slope and 4 is the y-intercept

Answer 3

If you put your equation in y = mx + b form, the slope is in the m position and the y intercept is in the b position. So first put the equation in y = mx + b form

Answer 4

x + 4y = 16
4y = -x + 16
y = -1/4x + 4

slope = -1/4
y intercept is (0,4)

to graph :
start at y intercept (0,4)....slope is -1/4, so you come down 1 (because it is negative) and then to the right 4 (because it is positive), then down 1, then to the right 4.
Now the x intercpet can be found by subbing in 0 for y.
x + 4y = 16
x + 4(0) = 16
x = 16....x intercept is (16,0) ....keep following your slope and you will cross the x axis at (16,0)
