Find the x-intercept and y-intercept of the equation: 3x-y = -9

Mathematics

The x-intercept and y-intercept of the equation: 3x - y = -9 is -3 and 9 respectively.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

We have equation:

3x - y = -9

The above equation represents a linear equation;

The equation can be written as:

y = 3x + 9

To find the x-intercept plug y = 0

x = -3

To find the y-intercept plug x = 0

y = 9

Thus, the x-intercept and y-intercept of the equation: 3x - y = -9 is -3 and 9 respectively.

Drag each tile to the correct location on the table. Each tile can be used more than once, but not all tiles will be used. Lewis
son4ous [18]

The fill up for the 3rd  step is y - 250 =  340x.

  • The fill up of the 5th step is x = \frac{y-250}{340}
  • The fill up of the 6th step  is \frac{8750-250}{340} = 25 = x, \frac{8750-250}{340}= 34 = x
  • The justification for the 2nd step is subtraction PE.
  • The justification for the 4th step is division PE.

<h3>What is the simplification  about?</h3>

Note that:

y-250 = 250 + 340 x - 250

y = 250 + 340x.

Make x the subject of the formula:

y - 250 =  340x.

then y-250/340 = x

Then  x = \frac{y-250}{340}

The justification for the second step is subtraction property of equality because it undergoes subtraction and the collection of like terms and then subtracting them from one another as shown below:

y-250 = 250 + 340 x - 250

y= 250 + 340x - 250 + 250

Note that (-250 + 250) = 0

y = 250 + 340x.

Lastly, The fill up of the 6th step is substitution of the amount of money  saved and  then simplifying it.
