using the slope formula find the slope of the line through the points (0,0) and (3,9) use pencil and paper explain how you can use mental math to find the slope of the line

Answers

Answer:

The answer is 3

Step-by-step explanation:

The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3.

What is the slope?

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,

Slope = (y₂ - y₁)/(x₂ - x₁)

Since the given line is passing through (0,0) and (3,9).

Slope = (9 -0)/(3 - 0)

Slope = 3

Since the line is passing through the origin (0,0) so we can do it by mental math to divide y and x coordinate directly like 9/3 = 3.

Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3".

x=8.5 because angle B and angle D are congruent using alternate interior angles theorem. so you would find the measure of B by adding 50+45 to get 95, then subtract 95 from 180 to get 85 degrees for angle B. Now your equation is 10x=85 so if you divide 85/10 you get x=8.5! hope this helped :)

Answer:

x = 5°

Step-by-step explanation:

Because of the given congruency,

Angle A = Angle D = 50° = 10x

10x = 50

x = 5°

i dont get it hope it helps

Answer: x= -10

Step-by-step explanation:

Let's solve your equation step-by-step.

6x−9=8x+11

Step 1: Subtract 8x from both sides.

6x−9−8x=8x+11−8x

−2x−9=11

Step 2: Add 9 to both sides.

−2x−9+9=11+9

−2x=20

Step 3: Divide both sides by -2.

−2x /-2= 20/-2

x=−10

Answer:

x=−10

Answer:

For the first question, the slope is -3.

For the second question, the point is (-6,7)

Step-by-step explanation:

In point-slope form, to identify the slope, its the number that's before the parenthesis, which in this case, its -3.

In point-slope form, to identify the points, its the number that replaces y1 and x1, which in this case, its -7 and 6. However, in point-slope form, the numbers are the opposite of what they are. For an example, in this equation, -7 is negative, buts its point would actually be positive.

Esto es igual a...
53 <—está del lado derecho, se queda igual

Write an equation in slope-intercept form of the line with slope 3/4 that contains the point (-4,1)

Answers

Answer:

y = 3/4x + 4

Step-by-step explanation:

to put it into slope intercept form, you need to find the y intercept or b becasue the slope intercept form is y = mx + b where b is the y intercetpt and m is the slope. To find b you insert the points you were given so 1 = -4(3/4) + b

which simplifies to 4 = b so then you can put in your slope and y intercept into slope intercept form
