6:15 and 8:20 are examples of additional equivalent ratios.
Step-by-step explanation:
The table is:
<u>Books (x) Cost (y)</u>
2 5
4 10
From the table, the ratio Books : Cost is 2:5 or 4:10. Equivalent ratios are obtained, using a graph, from the plot of the line that pass through these two points. In the figure attached, this line is shown. There, it can be seen that ratios 6:15 and 8:20 are equivalent to those from the table.
Answer:
Step-by-step explanation:
(1) A typical form of equation of a line is:
with, is slope and
is y-intercept.
(2) Another straight line has equation in form of:
with is slope and
is y-intercept
(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:
x
= -1
(4) Transform the given equation of original line into typical form:
<=>
