Which expression gives the distance between the points (4,6) and (7,-3)?​
Stella [2.4K]

Answer: The distance between is 13

Step-by-step explanation:

The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula

d = √  ((X2-X1)2+(Y2-Y1)2)

d = √ (4-4)2+(-6-7)2

d = √ ((0)2+(-13)2)

d = √ (0+169)

d = √ 169

The distance between the points is 13

2. What is the slope of the graph of 4x + 5y = 10?
Temka [501]

Answer:

-0.8 or -4/5

Step-by-step explanation:

You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:

4x + 5y = 10

5y = -4x + 10

y = -4/5x + 2

So your slope is -4/5.

Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.

Given the point (10, 25) and m = 2.5 , write the equation for the function m(t) point-stope form.
dalvyx [7]

Answer:

the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.

Step-by-step explanation:

Given

Point (10, 25)

Slope m = 2.5

To determine

Write the equation for the function m(t) point-stope form.

We know that the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

In our case:

  • m = 2.5
  • (x₁, y₁) = (10, 25)

so

substituting the values m = 2.5 and the point (10, 25) in the equation

y-y_1=m\left(x-x_1\right)

y - 25 = 2.5 (x - 10)

Therefore, the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.
