I did 6 problems for you. You can now do the other 4 problems and see how I did it. You need to have the same denominator and the add the fractions together.
(6-8)/(1+2)= -2/3 the answer to the question
Answer:
y = 2x -3
Step-by-step explanation:
y = 2x + b
plug the point in to the formula and solve for b
17 = 2 x 10 + b
b = -3
Use this to write the formula y = mx + b
m is slope
I think that it is the first line. I am not really sure what the question is asking so I may be wrong. Sorry if I can’t help
Answer:
the constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
