To find the equation of this line in slope-intercept form (y = mx + b, where m is its slope and b is its y-intercept), we naturally need the slope and the y-intercept. We can see that the line intersects the y-axis at the point (0, 4) so our y-intercept is 4, and the line rises 4 along the y-axis for every 2 it runs along the x-axis, so its slope is 4/2 = 2. With this in mind, we can write the line's equation as
y = 2x + 4

Answer:
(0,-4) (5,0)
Step-by-step explanation:
4x-5y=20
First, we must put the equation into slope intercept form: y= mx+b
5y=4x-20=y=4/5x-4
The y intercept, by definition, is b. In this scenario, b is -4.
One ordered pair that works is (0,-4).
Also, we can find the ordered pair for the x intercept. By definition, the x intercept is the value of x when y equals zero. hence, we substitute 0 for y and then we can find an ordered pair that works and solve for x!:
- 0=4/5(x)-4= 4=4/5x
- 4x=20
- x=5
Therefore, (5,0) works as well!
Answer:
Options 1 and 4 are arithmetic
Step-by-step explanation:
Arithmetic means that you are adding or subtracting a number in a sequence.
For option 1, we are adding 2 every time.
-3 + 2 = -1 -1 + 2 = 1 1 + 2 = 3
For option 4, we are subtracting 7 every time.
32 - 7 = 25 25 - 7 = 18 18 - 7 = 11
Option 2 is geometric. Geometric means you are multiplying or dividing by a number in a sequence.
2 * 3 = 6 6 * 3 = 18 18 * 3 = 54
Option 3 is actually quadratic. This is similar to a arithmetic, except instead, the amount added to the number is multiplied by 2 every time.
1 + 2 = 3 (2 + 2 = 4) 3 + 4 = 7 (4 + 4 = 8) 7 + 8 = 15
