ANSWER
The coefficient of y is
EXPLANATION
The first equation is
We can rewrite this equation in the slope intercept form to get,
We divide through by 10 to get,
The slope of this line is
and the y intercept is
Let
be the coefficient of y in the second equation.
Then, we have
We rewrite this equation too in slope intercept form to get,
Dividing through by
gives,
For the two equations to have infinitely many solution, then they must have the same slope and y intercept.
This means, that,
This implies that
Therefore the coefficient of y must be 2.
Top right i think because it looks like its non proportional
When you look at this problem you have to think, how many teaspoons do you need for 1 cupcake so you would divide 3 by 15 and get .....
Answer:
C
Step-by-step explanation:
c is the answer to your question
Make a line of best fit then find the slope and y intercept. put it into the y=mx + b form.
m=slope
b=y intercept
