Okay so if the graphs are parallel they’re going to have the same slope. so for example, 2a has y=3x+4 and y=3x+7.. those would be parallel because they both have 3x (the slope). The lines will be perpendicular when the slopes are the opposite reciprocal of one another. So on 2e you have one slope as -1/3 and the other as 3. That would be perpendicular. The opposite reciprocal just means that it will be the opposite sign (positive or negative) and you will basically flip the numbers ( 3/1 turns into 1/3). You’ll know if they are neither because the slope won’t follow any of these patterns. Some of them you may have to do an extra step, like 2b you need to get Y by itself before you can compare slopes
Answer:
Step-by-step explanation:
Find the diagram to the question attached.
The standard equation of a line in point-slope form is expressed as:
where:
m is the slope of the line
is coordinate point on the line
First is to get the slope of the line.
If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)
Hence the slope is -3
Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)
Hence the equation of the line in point-slope form is
Answer:
.6
