Answer:

Solution: (x, y) = (-1, 3)

Step-by-step explanation:

When graphing an equation written in slope-intercept form, it is usually convenient to plot the y-intercept, then use the value of the slope to work from there to find another point.

<h3>y = -x +2</h3>

The y-intercept is +2, meaning that the point (0, 2) is on the line. The coefficient of x is -1, so the line will go down 1 unit (-1) for each unit to the right. Conversely, it will go up one unit for each unit to the left. Thus points (1, 1) and (-1, 3) are both on this line.

You can continue in like fashion to find other points on the line. If you're drawing the graph by hand, you may want points that are 5 or more units apart, so you might choose one that is right 5 and down 5: (5, -3).

<h3>y = 4x + 7</h3>

As with the other equation, it can be convenient to start with the y-intercept, (0, 7). The slope of 4 tells you the line goes up 4 units for each unit to the right. That makes the point (1, 11) be a point on the line. However, it is beyond the edge of the graph you're given.

So, it will work better to go the other way: 1 unit left and down 4 units to (-1, 3) or (-2, -1). You may have noticed that the point (-1, 3) is on both lines, hence is the solution to the system.

Answer:

  A.  5

Step-by-step explanation:

The base AB is twice the length of the midsegment CD.

  8n +10 = 2(5n)

  8n +10 = 10n . . . . . eliminate parentheses

  10 = 2n . . . . . . . . . subtract 8n

Answer:

Step-by-step explanation:

The sum of the ages of a Mother and her son is 78 , three years ago the mother is five times as old as the son, what is their present ages?

To solve this , let the age of the mother be x and the age of the son be y , from the first statement :

x + y = 78

Three years ago , the mother will be x- 3 and the son will be y - 3 , from the second statement:

x - 3 = 5 ( y-3)

x- 3 = 5y - 15

x - 5y = -12

The resulting equations are

x + y = 78

x - 5y = -12

This is called a simultaneous linear equation , that means it is a linear equation.

The side of a square is xcm , if the difference between the area and the perimeter is 12 , find the legth of its side.

Interpretation:

The formula for the area of a square is l^{2} and the perimeter is 4l , from the question , we have

x^{2} - 4x = 12

This is not a linear equation , it is simply a quadratic equation , so the situation is non linear
