What happens to the slope when a line gets close to horizontal

It gets closer to 0.

The set of points whose coordinates satisfy an equation is called what the of the equation

Just took the vocab test the answer is graph.

The line given by the equation y equals 7x - 4 is perpendicular to the line given by which of the equations below

3

What is the slope of the line given by the equation y equals 3x Enter your answer as an integer or fraction in lowest terms

-2

How to find the slope of a line x equals -12

The equation for the slope of a line is y=mx+b

A horizontal line has a rise which is

The slope is 0. If it were vertical, the slope would be undefined.

APEX ZERO

How do you find the equation of a tangent line

In order to find the equation of a tangent line you must take the derivative of the original equation and then find the points that it passes through.

Find the quotient Enter your answer in lowest terms in the box below as a fraction using the slash mark for the fraction bar

43/48

What is the slope-intercept form of the equation through negative 2 5 parallel to y equals a negative x subtract 1

Since the line that passes through (-2, 5) it is parallel to the line with equation y = -x -1 and slope -1, then its slope is also -1, as parallel lines have the same slope.

In order to write the point-slope form of that line, we use the slope m = -1 and the point (x1, y1) = (-2, 5), such as

(y - y1) = m(x - x1)
y - 5 = -1(x - -2)
y - 5 = -1(x + 2)
y - 5 = -x - 2 (solve for y to obtain the slope-intercept form of the equation of the line)
y - 5 + 5 = -x + 5 - 2 (add 5 to both sides)
y = -x + 3

Thus, the slope-intercept form of the line that passes through (-2, 5) and parallel to the line with equation y = -x -1, is y = -x + 3.

If you are given the graph of a line in an xy-plane and its corresponding equation you can be sure that the coordinates of every point on that line will satisfy the equation

Yes, I'm confident of that.

What is vertical what is horizontal

Vertical is a straight line that goes up and down. Horizontal is a straight line going left to right.

What is the slope of the line that passes through the points 2 1 and -4 -5

Points: (2, 1) and (-4, -5)

Slope: (1--5)/(2--4) = 1

The slope of a line is 2 3 what is the slope of a line that is parallel to it

if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.

Which point lies on the line described by the equation below

That of course would depend on the straight line equation that has not been given and so therefore an answer is not possible.
