Answer:
Step-by-step explanation:
The graph of a linear relationship consists of the x and y values. The y values are plotted on the vertical axis against the x values on the horizontal axis. A change in the values of x lead to a corresponding change in the value of y. The correct options are
. I. The graphs of all linear relationships are a line. They are sometimes called straight line graphs
III. The tables of all linear relationships have a constant rate of change. This represents the slope
The true statement is
I and III only

x+8 10

2x-5 14
10(2x-5)=14(x+8)
20x-50 = 14x+112
20x-14x = 112+50
6x = 162
x= 162/6
x=27.....

Answer:
9
Step-by-step explanation:
Given
p(x) = 5x² - 3x + 7 ← substitute x = 1
p(1) = 5(1)² - 3(1) + 7 = 5(1) - 3(1) + 7 = 5 - 3 + 7 = 9
Answer:
The top left graph.
Step-by-step explanation:
That is because it goes through y=-2
