The two points that lie on a line with an undefined slope are a) (-2,-3) and (2,-6) b) (-2,-3) and (-6, 2 c) (-2,-3) and (2,0) d) (-2,-3 )and (-2,6)

Answers

Answer 1
Answer:
When you know 2 points on a line, the slope of the line is

            (difference in y-values) / (difference in x-values).

The slope of the line that includes the points (-2,3) and (-2,6) ...
choice-d ... is
                         (6 - 3) / (-2 - -2)  =  3 / 0 .

Division by zero is 'undefined'.

(On a graph, these two points are on a vertical line.)


Answer 2
Answer: The slope of the line that includes the points (-2,3) and (-2,6) ...
choice-d ... is
                         (6 - 3) / (-2 - -2)  =  3 / 0 .

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the number be n = 3/7

The equation A = n²

Substituting the value for n in the equation , we get

A = ( 3/7 )²

On simplifying the equation , we get

A = ( 3 )² / ( 7 )²

The value of A = 9/49

Therefore , the value of A is 9/49

Hence , the equation is A = 9/49

Seven times a number increased by three is 38

n-the\ number\n\n7* n+3=38\n7n+3=38\ \ \ \ |subtract\ 3\ from\ both\ sides\n7n=35\ \ \ \ |divide\ both\ sides\ by\ 7\n\n\boxed{n=5}
So,

If we translate this into mathematical form, we get
7n + 3 = 38

Subtract 3 from both sides
7n = 35

Divide both sides by 7
n = 5
