Answer:
y = - 
x - 
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 5) and (x₂, y₂ ) = (3, - 6)
m = 
= - , then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, - 5 ) , then
- 5 = - + c ⇒ c = - 5 + = -
y = - x - ← equation of line
When you are trying to figure this out put them into a list vertically. Remember, ONE X CAN'T HAVE TO Y's BUT ONE Y CAN HAVE MULTIPLE X's, But dont worry about the y's right now. Lets focus on the x's.
Ask yourself, Are there 2 or more x's that are the same value?
Yes) Continue to next step
No) It's a function :)
If there are 2 or more of the same x value, ask your self now if those x's have different y Values.
Yes) It is not a function, one x can not have more that 1 y value
No) Its a function :)
An expression having five terms which is equivalent to above term is :
Answer:
3/2 or 1.5 or 1 1/2
Step-by-step explanation
To divide, you must switch the -1/4 to its reciprocal which is -4/1 and then multiply the fractions (-3/8 * -4/1) and since negative - negative = positive. It's a positive.
of point B is equal to of point A. Correct option A).
<u>Step-by-step explanation:</u>
Here we have , a straight line in the graph between x-axis & y-axis . There are two points given here, A and B which lie in same line . Equation of line :
, passing through origin . General equation of a line is :
, where m = slope of line , c = x intercept , comparing this equation to to equation of line given in graph we get that m = 3/4 & c =0.
Useful info from here is slope = 3/4 . We know that slope = tan(theta) i.e.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
, which is constant i.e. ratio of y over x is a constant .Hence , of point B is equal to of point A. Correct option A).
