Write an equation of the line that passes through a pair of points (-5, -2), (4, 5)
Answers
First of all we need to find the slope. We can use the equation below.
The ones and twos just represent a y or x value from one of the ordered pairs, so for example on ordered pair could represent the ones(note that the ones and twos can be switched and the slope will remain the same).
In our case we will have (-5,-2) be (
Therefore the slope of our line is 7/9.
------------------------------------------------------------------------
Now we need to find the y-intercept to have the equation for our line. We will put the slope and two points from the line into slope intercept form and solve for b (we will use (4,5)).
5=4(7/9)+b
5-b=3 1/9
5+(-b)=3 1/9
-b=-2 1/9
b=2 1/9
Now that we have our value for b we will put it in slope intercept form.
y=7/9x+(2 +1/9)
I hope this helps!
First thing is to find the slope using the formula m = Δy ÷ Δx
m = 5 - (-2) ÷ 4 - (-5)
Now we simplify
m = 7 ÷ 9
Our equation so far is y = 7/9x + b. Now we can substitute the values of x and y from a point to figure out the answer. The equation here uses the point (4,5)
5 = 7/9 · 4 + b
Get b on one side
5 - 28/9 = b
Simplify
b = 1 + 8/9
That makes the equation of the line y = 7/9x + (1 + 8/9)

What form is the diagonal cross-section of a dice?
Slicing the cube with this aircraft creates a moving segment that may be a triangle, but not an equilateral triangle; it's miles a scalene triangle. note that if any two decided-on factors are equidistant from the original vertex, the move section might be an isosceles triangle.
How do you discover the diagonal attitude of a cube?
Use the trigonometric formula c^2 = a^2 + b^2 – 2ab cos C to resolve the unknown perspective of this triangle. C=1 and each a and b are equal to √three/2. Plugging those values into the equation, you'll determine that the cosine of your unknown angle is 1/three.

Answer:
b=-5
Step-by-step explanation:
3b+2-6b=32+5b-2b(first you should collect like terms on each side.) so
3b-6b+2=32+5b-2b (lessen thing by both sides.)
-3b+2=32+3b (then you collect terms to one side)
-3b-3b=32-2
-6b=30 (you divide both sides by 6)
-b=5 (since b cannot be a negative u divide both sides by -1)
so..b=-5
