First find the slope m. slope formula: 
Let's use (0, -20) for x1 and y1; and (2, 10) for x2 and y2
= 
= 
Now find the y-intercept: the point where the graph crosses the y-axis. The y intercept always has an x value of 0. So -20 is the y-intercept
Use the slope formula 
. Slope=m, y-intercept = b
y = 15x - 20
y is the money in the bank account in dollars
x is the day
Answer:
Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.
Hope it helped u if yes mark me BRAINLIEST!
Tysm!
Answer: b
7(b-1)/b less than or equal to 0
Step-by-step explanation:
If you were working with a flat rectangle and you were given the diagonal,
you'd want to use the Pythagorean theorem to choose two sides whose
squares would add up to the square of the diagonal.
It works exactly the same with a 3-D box. We need three dimensions for
the box, whose squares add up to the square of the diagonal between
opposite corners. That's (4)² = 16.
So (L)² + (W²) + (H²) = 16 . From there, you're completely free to pick any
numbers you want, just as long as their squares add up to 16. There are
an infinite number of possibilities. Here are a few:
1 x 1 x √14
1 x 2 x √11
2 x 2 x √8
2 x 3 x √3
1 x 3 x √6
