The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.

What is the equation of a line passing through two points?

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

$\rm (y - y_2) = \left ((y_2 - y_1)/(x_2 - x_1) \right ) (x - x_2)$

The table represents some points on the graph of a linear function.

3.5 -21

Take two points from the table, then the points are (-7.5, 12) and (-3.5, 0). Then the equation of the line is given as,

y - 0 = [(-3.5 + 7.5) / (0 - 12)](x + 3.5)

y = - (1/3)(x + 3.5)

3y = - x - 3.5

x + 3y + 3.5 = 0

The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.

Answer:

y=-3x-10.5

Step-by-step explanation:

Let's use the first set of numbers.

-7.5 and 12

-3.5 and 0

Our rise here is -12 and run is 4. So, our slope is -3.

Now we just need our intercept.

y = mx + b

y = -3x + b

0 = -3(3.5) + b

b = -10.5

Four expression are shown below 1. 2(2x^2-2x-60)
2. 4(x^2-x-30)
3. 4(x+6)(x-5)
4. 4x(x-1)-120

The standard form of a linear equation is ax by = c. if b = 0 and a and c are positive, which best describes the graph of this equation? the graph is a vertical line. the graph is a horizontal line. the graph is a line with a positive slope. the graph is a line with a negative slope.

Answers

I think the correct answer from the choices listed above is the first option. The standard form of a linear equation is ax + by = c. If b = 0 and a and c are positive, then the graph is a vertical line which will be equal to c/a. Hope this answers the question. Have a nice day.
