Gradient of line AB (3,7) and (5,11)​

Mathematics
2 answers:
Delicious77 [7]3 years ago
7 0

Use the slope/gradient formula below:

\large \boxed{m =  \frac{y_2 - y_1}{x_2 - x_1} }

This formula is for when we want to find the gradient when we have two given points. (We also call it Rise Over Run or changes of y over the changes of x.)

We are given two points which are (3,7) and (5,11). Substitute these points in the equation. (the ordered pairs are in (x,y) and not (y,x))

\large{m =  \frac{11 - 7}{5 - 3} } \\  \large{m =  \frac{4}{2}  \longrightarrow  \boxed{m = 2}}

Hence, the gradient of AB is 2.

Answer:

Gradient is change in y over change in x.

gradient = y1-y2 ÷ x1-x2

=7-11 ÷ 3-5

=-4 ÷ -2

=2

5/6 , 7/18 , 11/24 , 19/36 in descending order
motikmotik

Answer: 5/6, 19/36, 11/24, 7/18

Step-by-step explanation:

Descending order is going from largest to smallest. We can do this by comparing the fractions. We make all the fractions have the same denominator. Then we will see which has the larger numerator.

\frac{5}{6} , \frac{7}{18} , \frac{11}{24} , \frac{19}{36}

A common denominator we can use is 72, since it is a common multiple.

\frac{60}{72} ,\frac{28}{72}, \frac{33}{72}, \frac{38}{72}

Now that all the numbers have the same denominator, we compare to see which number is largest to smallest.

\frac{60}{72} ,\frac{38}{72} ,\frac{33}{72} ,\frac{28}{72}

With our descending order, let's put it back into the original fractions.

\frac{5}{6} ,\frac{19}{36} ,\frac{11}{24} ,\frac{7}{18}
