Answer:
p = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 4
m = 
with (x₁, y₁ ) = (- 3, p ) and (x₂, y₂ ) = (- 4, 0 )
m =
=
=
= p = - 4
Answer:
Exponential
Step-by-step explanation:
By visual inspection the graph generated by the points plotted is an exponential graph as the graph curves upward. The graph is also continous and differs from either a decreasing or increasing Linear graph, which shows a straight best of fit pattern. Hence, the graph most closely represents an exponential graph from visual examination.
substitution method
Step-by-step explanation:
- use second equation
- make x subject of the formula
- put it back in the first equation
- solve to find the value of y
- substitute y value in any equation between the two.
- then you get x value
4 is the nearest integer
as a decimal this number would be 3.5, which would round up to 4.
