Write an equation for the data in the table. Identify your variables.
1 answer:
First find the slope m. slope formula:
Let's use (0, -20) for x1 and y1; and (2, 10) for x2 and y2
=
=
Now find the y-intercept: the point where the graph crosses the y-axis. The y intercept always has an x value of 0. So -20 is the y-intercept
Use the slope formula . Slope=m, y-intercept = b
y = 15x - 20
y is the money in the bank account in dollars
x is the day

The Triangle sum theorem states that the sum measures of the interior angles of a triangle is 180 degree
<em><u>Solution:</u></em>
We know that,
The Triangle Sum Theorem states that if you add all three interior angles, those are the angles inside the triangle, they would always add up to 180 degrees.
It is easy to remember that we add the three angle measurements to get 180 degrees because of the word sum in the name of the theorem. To make it short and sweet:
Consider a triangle with interior angles a, b, and c. Then we can say,
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem
