The required equation is: $y= 7x$

Option C is correct.

Step-by-step explanation:

The proportional relationship can be found using the equation: $y=k\,x$

where x and y are the points and k is the constant of proportionality.

We need to find k.

From the graph given, we can locate points x and y:

x=5, y= 35 then k would be:

$y=kx\\k=y/x\\k=35/5\\k=7$

x=10, y=70 then k would be:

$y=kx\\k=y/x\\k=70/10\\k=7$

For each values of x and y, the constant of proportionality k is 7

So, the required equation is: $y= 7x$

Option C is correct.

What is the slope of the line passing through the points (-1,-7) and (-9,-2)?

nalin [4]

Answer: m = -5/8

Step-by-step explanation:

The general equation for slope is rise over run, also known as:

m=(y2-y1)/(x2-x1)

From the points (x, y), we can get all the variables we need.

(-1, -7) gives us x1 = -1 and y1 = -7

(-9, -2) gives us x2 = -9 and y2 = -2

If we plug all the values in, we get:

m = (-2 - (-7))/(-9 - (-1))

m = (-2 + 7)/(-9 + 1) the negatives cancel

m = (5)/(-8)

m = -5/8

Find the values of x and y.

kupik [55]

Answer:

x=6, y=75

Step-by-step explanation:

Since the diameter of the circle is a perpendicular bisector to the chord, x and 6 must be equal and therefore x=6. It also bisects the arc, meaning that y=75. Hope this helps!

The vertex angle of an isoceles triangle is 8 times the measure of the base angle. find the measure of the base angle

Yuki888 [10]

For this problem, if we used b to represent your base angle measurement, you would add 8b+2b and set it equal to 180. This is because the measure of the vertex angle is 8 times the base angle measurement, so we had to multiply b by 8. We also had to add it to the other angle measures, so the other angle measures are represented as 2b since they are the same length. We then have to set this equal to 180 since that measures of a triangle must add up to 180. Then we combine like terms on our “b” side to get 10b=180. Then we divide both sides by 10 and we get b=18, which is the measure of our base angle.
