Which graph represents a proportional relationship?

Mathematics

Vadim26 [7]3 years ago

Answer:

The one shown in the photo

Step-by-step explanation:

A proportional relationship is one in which the relationship increases steadily, which looks like a straight line when graphed. Also, the line should pass through the <em>origin</em>, which is the point (0, 0) on a graph.

The graph shown increases steadily (it's a straight line), and passes through the origin (point 0,0) as well. So, it's proportional. Hopefully that's helpful! :)

What information does the ordered pair (3, 87) represent?
mafiozo [28]

<span>The 3 (x-coordinate) indicates that from the origin (0,0) in the cartesian plane, you have traveled four units to the right along the x-axis(the horizontal axis). </span>

<span>The 87 indicates that you traveled 87 units up in the y-axis(vertical axis), in line with the point 3 in the x-axis.This number is the y-coordinate, the second number in the ordered pair. </span>

Bad White [126]
The total charge for Juan in the parking spot would be $2.25.

Since we know one of those 8 hours is 50 cents, we can multiply .25 by 7 which would give us 1.75. Then we know that the first hour, as stated above, is going to be .50, so we can add that to our total which is 2.25.

Hope this helps!

Answer:

y=[-4]x+[10]

Step-by-step explanation:

For a line to be perpendicular to another it must have the reverse reciprocal of the opposite line, to find the reverse reciprocal you take your slope, flip the numerator and denominator, and multiply it by -1.

The slope \frac{1}{4} turns into \frac{4}{1} and is then multiplied by -1 to become \frac{-4}{1} which can be simplified down to: -4

Now that we know the slope we need the line to pass through a point, so we will use point slope form:

y-y1=m(x-x1)
Substitute in our slope and point values:

y-2=-4(x-2)

Now solve for y:

y-2=-4(x-2)\\y-2=-4x+8\\y=-4x+10

Then you will find that line y=-4x+10 runs perpendicular to y=\frac{1}{4}x-8 and intersects point (2,2).
