Write the equation in standard<br> form of the line that has<br> x-intercept 6 and y-intercept -2.
zysi [14]

Answer:

<em>x - 3y = 6</em>

Step-by-step explanation:

<u>Equation of the line in intercept form</u>

The intercept form of the equation of a line is:

\displaystyle \frac{x}{a}+\frac{y}{b}=1

Where:

a = x-intercept

b = y-intercept

The standard form of a line is:

Ax + By = C

The given line has a=6 and b=-2, thus:

\displaystyle \frac{x}{6}+\frac{y}{-2}=1

Multiplying by 6:

x - 3y = 6

This is the required standard form of the line.

Thus, the standard form of the line is:

x - 3y = 6

Goodmorning all help me guys​
kotegsom [21]

Answer:

Step-by-step explanation:

1) Distance covered by motorcycle = x

y  = 50 + (x -2)*10

2)Distance traveled = 5 km

y = 50 + ( 5-2) *10

  = 50 + 3*10

  = 50 + 30

  = 80

Seth will be paid Php 80

3)  y = 120

50 + (x - 2)* 10 = y

50 + (x -2) *10 = 120

50 + 10x - 2*10 = 120

50 + 10x - 20  = 120

30 + 10x = 120

       10x = 120 - 30

       10x = 90

           x = 90/10

x = 9

A passenger can travel 9 km.

4)y = (x - 2)*10

 y = 10x - 20

20 + y = 10x

     20 = 10x - y

10x - y = 20      {Ax + By = C form}
