Just keep going down 3? I don't see how math is needed here. I'm also not sure if we can create graphs.

Use the table to determine whether the relationship is proportional. If so, write an equation for the relationship. Tell what ea

Neporo4naja [7]

Answer:

y = 25x, proportional relationship

Step-by-step explanation:

Let "x" = number of hours read (replace with "h" if that's the variable your teacher wants)

Let "y" = number of pages read (you can use any other variables if you want)

Let's first calculate the slope using $\frac{y_{1} - y_{2}}{x_{1} - x_{2}}$ with any two points, I'm going to use (2, 50) and (3, 75):

$\frac{y_{1} - y_{2}}{x_{1} - x_{2}} = \frac{50 - 75}{2 - 3} = \frac{-25}{-1} = 25$

Our slope is m = 25.

Now we can use the point-slope form $y-y_{1} = m(x-x_{1})$ with our slope and any point (I'll use (2, 50)) to figure out the equation:

$y-y_{1} = m(x-x_{1}) \\ y-50 = 25(x-2)$

Simplify:

$y-50 = 25(x-2)\\y-50 = 25 x -50\\ y = 25x$

Since the slope is positive, the relationship is proportional.

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.

SCORPION-xisa [38]

The equation of line is:

$y = \frac{-3}{2}x+1$

Further explanation:

The standard form of equation in point-slope form is:

$y = mx+b$

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

$3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5$

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

$y = \frac{-3}{2}x+b$

To find the value of b, putting the given point (4,-5) in equation

$-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1$
