Write an equation through the points (-3,7) and (1,-1)​
Aliun [14]

The slope is -2.

The slope is the rise over the run. Because the line goes down from left to right, it makes the value negative. For every one the it moves to the right, the line goes down two units.

Please help!! ABCD is a square. If AC = 26, Find BC<br><br> a. 7<br> b. 26<br> c. 12<br> d. 18.4
myrzilka [38]
Since this is a square and we have the diagonal, we can use the formula Square root of 2 times d/2 where the diagonal is d, we can find the side (sqrt 2 * d/2)
sqrt 2 * 26/2 = 18.38. Rounding our decimal we get 18.4, so the answer is d. Hope this helps

Identify the slope by converting standard form into slope-intercept form.<br> 3x - 2y = - 14
Talja [164]

Answer:

3/2

Step-by-step explanation:

3x-2y=-14

2y=3x-(-14)

2y=3x+14

y=3/2x+14/2

y=3/2x+7

y=mx+b where m=slope and b=y-intercept,

so the slope is 3/2.

Each vertical cross-section of the triangular prism shown below is an isosceles triangle.
son4ous [18]

Answer:   The height is 3  units.

Step-by-step explanation:

By using the give figure we can form right angle out of the whole figure  with a base of  4  and an hypotenuse of 5.

By using this information we can use the Pythagorean Formula to find the height

a^2 + b^2 =c^2     a= base, b = height and c will be the hypotenuse.

4^2 + b^2 = 5^2     Solve for B

16  + B^2 = 25  

-16               -16

    b^2 = 9    

    b = \sqrt{9}  

  b  = 3
