Answer:
The graph of the linear equation is attached below
Step-by-step explanation:
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.

Answer:
Independent
Step-by-step explanation:
Total length of 15 car train is 240 centimeters.
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.

Answer:
C: (8,11)
Step-by-step explanation:
The equation in slope-intercept form for the line with slope 1/2 and y-intercept -9 will be y = (1/2)x - 9.
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.

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
