Graph the line with the equation y=-2/5x+1

Answers

Answer:

Step-by-step explanation:

slope = -2/5

y intercept = (0,1)

The graph of the line y=-2/5x+1 is given below.

To graph the line with the equation y = -2/5x + 1, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope is -2/5, which means that for every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 2/5 units. The negative sign indicates that the line slopes downward from left to right.

The y-intercept is 1, which is the point where the line crosses the y-axis.

To plot the line, start by marking the y-intercept at (0, 1) on the coordinate plane. From there, use the slope to find additional points. For example, if you move 5 units to the right (because the denominator of the slope is 5) from the y-intercept, the y-coordinate will decrease by 2 units, giving you the point (5, -1).

What is the next step

Answers

Answer:

measure of angle ABC is 6 degree.

Step-by-step explanation:

After you found x, you'll plug it in the equation of the angle it's asking for.

Measure of angle ABD, and you know measure of angle ABC = 4x-1.

4(1)-1 = 4-1 = 3

Measure of angle CBD = 2x+1.

2(1) +1 = 3

Measure of angle ABC is ABD + CBD

3 + 3 = 6

Answer:

6°

Step-by-step explanation:

We know that is 4x - 1 + 2x + 1

So it equals

or 6 ( 1) = 6°

Mr porter had eight parties at her house last year the number of guest at each party is shown below 15,19,9,27,21,21,10,14

Answer:

Step-by-step explanation:

Complete question

Mr porter had eight parties at her house last year the number of guests at each party is shown below 15,19,9,27,21,21,10,14. What is the median numbers of those parties

The median value is the value at the middle after rearrangement

On rearranging in ascending order

9, 10, 14, (15, 19), 21, 21, 27

Since there are two values in the middle, we will take the average of the numbers

Median = 15+19/2

Median = 34/2

Median = 17

Hence the median value is 17
