Complete Question:

If the point (2, 5) is a solution to the system of equations shown below, then determine the missing values of b and m. Show how you arrive at your answer.

1. y = 3x + b

2. y = mx + 9

Answer:

1. Intercept, b = -1

2. Slope, m = -2

Step-by-step explanation:

Given the following data;

Points on the line (x, y) = (2, 5)

To find the missing values;

Mathematically, the equation of a straight line is given by the formula;

y = mx + b

Where;

m is the slope.
x and y are the points
b is the intercept.

1. y = 3x + b

Substituting the value of x and y, we have;

5 = 3(2) + b

5 = 6 + b

b = 5 - 6

Intercept, b = -1

2. y = mx + 9

Substituting the value of x and y, we have;

5 = m(2) + 9

5 = 2m + 9

2m = 5 - 9

2m = -4

m = -4/2

Slope, m = -2

These triangles are similar and the sides are proportional. Which proportion correctly describes the situation below?

Veronika [31]

Answer:

Option (3)

Step-by-step explanation:

"If two triangles are similar, their corresponding sides are proportional."

We will check each proportionality ratio given in the options for the given property,

Option (1),

$\frac{QB}{DM}=\frac{DF}{QL}=\frac{LB}{MF}$

$\frac{3.5}{2}=\frac{5}{8.75}=\frac{10.5}{6}$

$\frac{7}{4}=\frac{4}{7}=\frac{7}{4}$

But $\frac{7}{4}\neq \frac{4}{7}$ .

Therefore, this option is not the answer.

Option (2),

$\frac{FM}{LB}=\frac{BQ}{MD}=\frac{QL}{DF}$

$\frac{6}{10.5}=\frac{3.5}{2}=\frac{8.75}{5}$

$\frac{4}{7}=\frac{7}{4}=\frac{7}{4}$

But $\frac{4}{7}\neq \frac{7}{4}$ ,

Therefore, this option is not the option.

Option (3),

$\frac{BQ}{MD}=\frac{QL}{DF}=\frac{BL}{MF}$

$\frac{3.5}{2}=\frac{8.75}{5}=\frac{10.5}{6}$

$\frac{7}{4}=\frac{7}{4}=\frac{7}{4}$

Therefore, this option is the answer.

Option (4),

$\frac{6}{10.5}=\frac{2}{3.5}=\frac{5}{10.5}$

$\frac{4}{7}=\frac{4}{7}=\frac{10}{21}$

But, $\frac{4}{7}\neq \frac{10}{21}$

Therefore, this is not the correct option.
