I need help on this one please

Mathematics
1 answer:
icang [17]3 years ago
6 0

Answer:

See below.

Step-by-step explanation:

The first group have 2 ordered pairs (0, 1) and (0, 5) in which there are 2 values of y linked to one value of x, which makes it a relation but not a function.  

In the second group each value of x is linked to one  and only one value of y which makes it a function.

A function is either a one-to-one ( like the second group) or a many-to-one relation.

A one-to-many relation as exists in the first group is a relation but it's not a function.

• 6x – 15y = 15<br> y=2 x - 1<br> 5
yuradex [85]

Answer:

Slope=  

2.000

0.800

​  

=0.400

x−intercept=  

2 /5

​  

=2.50000

y−intercept=  

−5 /5

​  

=  

−1

​  

=−1.00000

Step-by-step explanation:

STEP

:

Pulling out like terms

1.1     Pull out like factors :

  6x - 15y - 15  =   3 • (2x - 5y - 5)  

Equation at the end of step

:

STEP

:

Equations which are never true

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Equation of a Straight Line

2.2     Solve   2x-5y-5  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2x-5y-5  = 0 and calculate its properties
