This means the radius is 10 units. For it to be a circle, any point that lies on the circle is the same distance from the moving point to a fixed point (the centre). This distance is the radius.
As such, any other point that lies on the circle is 10 units from the centre as well.
Always, ALWAYS remeber this format: y = mx + b
In this equation, 'm' is the slope, and 'b' is the y-intercept
When you're trying to find a slope, remember that the equation is
When finding the rise and run, look at two points that are on the graph AND on the line as well. Essentially, make sure the points you're using are integers.
In this, case, the rise is -3, and the run is 2. This means that the slope is
Now we have the first part of our equation:
y = - + b
But wait! How do we find b?
Sometimes you have to input x in order to find it, but only when you're not supplied with a graph. In this case, all you have to do is look!
The point of the line that is on the y-axis is called the y-intercept.
In this graph, the y-intercept is -1
Now we have our complete equation!
y = - - 1
Good luck!
Answer:
Step-by-step explanation:
First of all, let us try to find out the equation.
We can easily observe from the graph the values of x and y intercept.
x intercept is the value where y coordinate is 0.
We can see that y is 0 at x = 4
So, x intercept (4, 0)
y intercept is the value where x coordinate is 0.
We can see that y is 1 at x = 0
So, x intercept (0, 1)
Now, we have 2 points for the equation of line.
Slope intercept form:
Slope of a line:
Putting the point (0, 1):
So, the equation becomes:
Let us try to put a point (0, 0) in the equation.
LHS becomes 0.
RHS becomes 1.
LHS < RHS (Only less than sign used because the line is dashed not solid)
So, the inequality is:
