Answer:

Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form:
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)
Perpendicular lines always have slopes that are negative reciprocals. For example, 2 and -1/2. 3/4 and -4/3.
To determine whether a line is perpendicular to
, we must first determine its slope. Rearrange the given equation into slope-intercept form:

From this, we can clearly tell that the slope (<em>m</em>) of the line is
.
The negative reciprocal of
is 2. Therefore, the slope of a perpendicular line would be 2.
Therefore, the correct answer option would be
.
I hope this helps!
Answer:
20, thats what is in your little box so that should be the answer
Answer:
-1
Step-by-step explanation:
Since this point is on the y-axis, the coordinates for this point must be (0, -1)
0.6 is just what it seems like. 3/4 needs to be turned into a decimal for it to be compared with 0.6. 3/4 equates to 0.75, so we can see that 0.6 < 0.75.
