The lowest common denominator is 21
Answer:
y=1/4x slope is 1/4
Step-by-step explanation:
add 1 to 2 to get 3 for the change in y, then add 4 to -2 to get 2 for the change in x, then put the change in y (1), over the change in x (4), to get a slope of 1/4
3(x-9)
when you distribute the equation you get
3(x)-3(9) which is the last answer
Answer:
