Answer:
A is correct
Step-by-step explanation:
Given: Table of x and y
x : 2 4 6 8
y : 3 4 5 6
Using two point find the slope:
(2,3) and (4,4)
Now we find slope using last two point
(6,5) and (8,6)
Slope is equal. Thus, The given relation is linear.
Hence, The relation represents a linear equation
So if an equation with two variables, you need to also two equations to solve the values of the variables. but if you knew the value of the one variable then onl one equation is need. for example an equation x + y = 20
where x = 5
then to solve the value of y, substitute the value of the equation
5 + y = 20
then transpose 5 to the other side
y = 20 - 5
y = 15
Answer:
4. Slope = 7 Y-intercept = 2
5. Slope = -1 Y-intercept = 4
6. Slope = 1/2 Y-intercept = -2
Step-by-step explanation:
7. Slope = 2/3 Y-intercept = 3
8. Slope = -3/4 Y-intercept = 1
9. Slope = 3/2 Y-intercept = 2
Really, really, hope I helped.
Using the quadratic formula we get
Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
