Answer:

y=2x-20

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=2(x-9)

y+2=2x-18

y=2x-18-2

y=2x-20

PLSS HELPP BRAINLIEST AND 65 POINTS pls do the graph too

Eddi Din [679]

Answer:

$\Large \boxed{ -x+65}$

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope m

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

$\displaystyle m=\frac{55-65}{10-0}=-1$

Use slope-intercept form

$y=mx+b$

$y=-1x+b$

b is the y-intercept, y-intercept is (0,65)

$y=-1x+65$

Which of the following is defined by a line parallel to one side of a triangle

Katarina [22]

Answer:

Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

Step-by-step explanation:

Triangular Proportionality Theorem states that:

If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.

Let us consider the triangle ΔABC as shown in attached figure.

$DE$ ║ $AC$

then

$\frac{BD}{DA} = \frac{BE}{EC}$

Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

The solution set to the inequality y<2x - 4 are shaded on the graph. Which point is a solution

BaLLatris [955]

Any set of numbers (x, y) for which this inequality is true is a solution.

For example, the point (1, -5) is a solution because fitting it into the inequality gives us

- 5 < - 2 which is true.

However, the point (3, 5) wouldn't be a solution because it would give us the inequality

5 < 2 which is not true.
