What the y-intercept of (8,0) and (3,7)
Anettt [7]

Answer:

\sf \bf y - intercept = \dfrac{56}{5}

Step-by-step explanation:

Y-intercept:

   (8,0)  ; x₁ = 8 & y₁ = 0

   (3,7)   ; x₂= 3  & y₂ = 7

  • First find the slope of the line.

      \sf \boxed{\bf Slope =\dfrac{y_2-y_1}{x_2-x_1}}

                  \sf = \dfrac{7 - 0}{3 - 8}\\\\ =\dfrac{7}{-5}\\\\=\dfrac{-7}{5}

 slope y-intercept form of the line:  y = mx + b

Substitute the slope and x and y in the above equation. We can choose anyone of the given points.

     0 = \dfrac{-7}{5}*8 + b\\\\0=\dfrac{-56}{5}+b\\\\\dfrac{56}{5}=b\\\\ \boxed{\bf b = \dfrac{56}{5}}

Write 12 1/3 as an improper fraction.
Julli [10]

Answer:

\frac{37}{3}

Step-by-step explanation:

12\frac{1}{3}

When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:

12*3=36

Then, add the numerator the the product:

36+1=37

Now, put the sum over the denominator to get your solution:

\frac{37}{3}

-

To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with 12\frac{1}{3}.

Divide 37 into 3:

12 with a remainder of 1

Put the remainder over the denominator:

12\frac{1}{3}

Therefore, our solution is correct!
