2) Find the slope of the line. (If an answer is undefined, enter UNDEFINED.)

Question

4x + 5y = 20

Answer 1

for the equation in the form
Ax + By = C, the slope is -A/B, so ....

or change it to the form y = mx + b, where the slope is m
4x + 5y = 20
5y = -4x + 20

y = ....

Answer 2

y= -4/5x +5

Answer 3

so the slope is -4/5

Answer 4

correct

Answer 5
