1 answer:

7 0

Find Slope:

$\text {Slope = } \dfrac{6-1}{7+3} = \dfrac{5}{10} = \dfrac{1}{2}$

Equation: y = 1/2 x + b

Find y-intercept:

At (7, 6),

6 = 1/2 (7) + b

6 = 3.5 + b

b = 2.5

Equation: y = 1/2 x + 2.5

Answer: y = 1/2 x + 2.5

Answer:

$7.7n=112.42$

$n=14.6$

Step-by-step explanation:

The product is the result obtained by multiplying two factors. Then, the sentence ""The product of a number n and 7.7 equals 112.42" can be expressed with the following equation:

$7.7n=112.42$

To solve for the variable "n", you has two apply the Division property of equality and divide both sides of the equation by 7.7

Therefore, the value of "n" is:

$\frac{7.7n}{7.7}=\frac{112.42}{7.7}\\\\n=14.6$
