How to graph y=3x-8​

Answers

Answer:

The graph of the linear equation is attached below

Step-by-step explanation:

y=3x-8​

To graph a linear equation , we use a table method

We take some random number for x  and find out y. Always assume some positive as well as negative numbers.

x     y=3x-8

-1        3(-1)-8= -11

0        3(0)-8=-8

1         3(1)-8= -5

The points for graphing are (-1,-11)  (0,-8)  and (1,-5)

The graph of equation y = 3x - 8 is shown in image.

Since, The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

We have to given that;

Equation is,

⇒ y = 3x - 8

Now, By comparing with the equation of line, we get;

y - intercept of graph = (0, - 8)

And, Slope = 3

Hence, The graph of equation y = 3x - 8 with y - intercept is shown in image.

If each car is 16 centimeters long, what is the length of a 15 car train

Answers

Total length of 15 car train is 240 centimeters.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, car is 16 centimeters long.

The length of a 15 car train = Length of each car × Number of cars

= 16×15

= 240 centimeters

Therefore, the length of 15 car train is 240 centimeters.

A system of linear equations includes the line that is created by the equation y = x+ 3, graphed below, and the line through the points (3, 1) and (4, 3). On a coordinate plane, a line goes through (0, 3) and (2, 5). What is the solution to the system of equations? (–1, 2) (1, 3) (8, 11) (9, 12)

Answers

Answer:

The solution to the system of equations is (8,11)

Step-by-step explanation:

A system of linear equations includes the line that is created by the equation y = x+ 3

The line through the points (3, 1) and (4, 3)

(x_1,y_1)=(3,1)\n(x_2,y_2)=(4,3)

Equation of line =y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

Equation of line =y-1=(3-1)/(4-3)(x-3)

Equation of line =y-1=2x-6

Equation of line =y=2x-5

On a coordinate plane, a line goes through (0, 3) and (2, 5).

(x_1,y_1)=(0,3)\n(x_2,y_2)=(2,5)

Equation of line =y-3=(5-3)/(2-0)(x-0)

Equation of line =y=2x+3

Plot all lines on graph

y = x+ 3 ---- Blue line

y=2x-5 --- Green line

y=2x+3  ---- Purple line

Write an equation in slope-intercept form for the line with slope 1/2 and y-intercept -9

Answers

The equation in slope-intercept form for the line with slope 1/2 and y-intercept -9 will be y = (1/2)x - 9.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is 1/2 and the y-intercept of the line is -9. Then the equation of the line is given as,

y = (1/2)x - 9

The equation in slope-intercept form for the line with slope 1/2 and y-intercept -9 will be y = (1/2)x - 9.

#SPJ2

Answer:

y = 1/2x-9

Step-by-step explanation:

y = mx + b

b = y-intercept

m = slope

so, if y = mx + b, then y = 1/2x - 9
