Answer:

not linear, degree 2

Step-by-step explanation:

The degree of this equation is the highest sum of the exponents of the variables in any given term.

Here, there is one variable term. The variables are x and y. They each have an exponent of 1, so the degree of the variable term is 1+1 = 2.

Since the degree of the equation is not 1, it is not a linear equation.

Which equations represents a line that is parallel to 3x-4y=7 and passes through the point (-4,-2)

insens350 [35]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x - 4y = 7 into this form

Subtract 3x from both sides

- 4y = - 3x + 7 ( divide all terms by - 4 )

y = $\frac{3}{4}$ x - $\frac{7}{4}$ ← in slope- intercept form

with slope = $\frac{3}{4}$

• Parallel lines have equal slopes, hence

y = $\frac{3}{4}$ x + c ← is the partial equation of the parallel line

To find c substitute (- 4, - 2) into the partial equation

- 2 = - 3 + c ⇒ c = - 2 + 3 = 1

y = $\frac{3}{4}$ x + 1 ← in slope- intercept form

Multiply all terms by 4

4y = 3x + 4 ( subtract 4 from both sides )

4y - 4 = 3x ( subtract 4y from both sides )

- 4 = 3x - 4y, that is

3x - 4y = - 4 ← in standard form

Choose the equation that represents a line that passes through points (-1, 2) and (3, 1).

maw [93]

Answer:

The answer is x + 4y = 7

Equation of a line is y = mx + c

Where m is the slope

c is the y intercept

Slope of the line between the points

(-1, 2) and (3, 1) is

Slope = 1-2/ 3+1 = - 1/4

Equation of the line using point

(-1, 2) is

y - 2 = -1/4(x + 1)

4y - 8 = - x - 1

x + 4y = 7

Hope this helps you

Answer: C. Keeps taxes lower for Georgians

Step-by-step explanation:

Since the road system allows the bulky products to be shipped inexpensively this must apply that the taxes are lower for georgians otherwise this might not have been the case.
