Answer:
y=x+6
Step-by-step explanation:
To find the slope: --> --> -->
Insert into the point-slope form: (y-7)=(x+4)
Solve: y-7=x-1 --> y=+6
Answer:
18 Outcomes
Step-by-step explanation:
Each time you flip the coin it has 2 outcomes (Heads or Tails) . Each time you pick a number it has 9 outcomes (1,2,3,4,5,6,7,8,9). So it is asking if you flipped a coin and picked a random number (1-9) at the same time, for whatever reason, you would have 18 outcomes. This is because for every number (1-9) you pick it has 2 different sides of the coin it could land on and vive-versa. Basically, for every coin side there are nine numbers and for every number there are 2 sides.
A linear equation is an equation with two variables whose graph is a line. The graph of the linear equation is a set of points in the coordinate plane that all are solutions to the equation. If all variables represent real numbers one can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.
If you want to graph a linear equation you have to have at least two points, but it's usually a good idea to use more than two points. When choosing your points try to include both positive and negative values as well as zero.
Example
Graft the function y = x + 2
Begin by choosing a couple of values for x e.g. -2, -1, 0, 1 and 2 and calculate the corresponding y values.
X Y = x + 2 Ordered pair
-2 -2 + 2 = 0 (-2, 0)
-1 -1 + 2 = 1 (-1, 1)
0 0 + 2 = 2 (0, 2)
1 1 + 2 = 3 (1, 3)
2 2 + 2 = 4 (2, 4)
Now you can just plot the five ordered pairs in the coordinate plane

At the moment this is an example of a discrete function. A discrete function consists of isolated points.
By drawing a line through all points and while extending the line in both directions we get the opposite of a discrete function, a continuous function, which has an unbroken graph.

If you only want to use two points to determine your line you can use the two points where the graph crosses the axes. The point in which the graph crosses the x-axis is called the x-intercept and the point in which the graph crosses the y-axis is called the y-intercept. The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).

The standard form of a linear equation is
Ax+By=C,A,B≠0
Before you can graph a linear equation in its standard form you first have to solve the equation for y.
2y−4x=8
2y−4x+4x=8+4x
2y=4x+8
2y2=4x2+82
y=2x+4
From here you can graph the equation as we did in the example above.
The graph of y = a is a horizontal line where the line passes through the point (0, a)
picture16
Whereas the graph of x = a is a vertical line that passes through the point (a, 0)

The area is measured in square units because it is the product of two units which gives square unit.
<h3>What is
area?</h3>
Area is the amount of space occupied by a two dimensional shape or object.
The area of a rectangular park is gotten from the productiif the width and length, hence:
Area = length * width
The area is measured in square units because it is the product of two units which gives square unit.
