What is the slope of a line that contains the points (1 -2) and (4, -3).

Naddika [18.5K]

Answer:

$-\frac{1}{3}$

Step-by-step explanation:

Use the definition of slope:

$m=\frac{y_2-y_1}{x_2-x_1}\\$

Replace the values in the equation and solve:

$m=\frac{-3-(-2)}{4-1} \\m=\frac{-1}{3}\\m=-\frac{1}{3}$

9 whole 2/3 + 4 whole 7/9=

scoundrel [369]

Answer

14 4/9

Turn 9 2/3 into an Improper Fraction

Multiply 9*3 and get 27. Now add 2 and get 29 (Denominator stays the same)

9 2/3 = 29/3

Turn 4 7/9 into an Improper Fraction

Multiply 4*9 and get 36. Now add 7 and get 43 (Denominator stays the same)

4 7/9 = 43/9

Add

29/3 + 43/9 = 130/9

Turn 130/9 into a Mixed Number (Divide)

130/9 = 14 4/9

Hope This Helps!

In the equation 3x+ 2 = 11 which number is the constant?

grigory [225]

Answer:

The constant is 2 and 11

Step-by-step explanation:

A constant is a number that always has the same value. In this equation 2 and 11 are the constants because they stay the same. 3x doesn't stay the same because 3 is multiplying x.
