Point-slope form is one way of describing a straight line. It is useful when you have a line to be described and you know the coordinates of one point on the line and its gradient (slope).
The point-slope form equation of a straight line for a slope, m, and known coordinate

is

.
So for your question you have <span>

</span> and slope = m = -1. You just put these numbers into the formula

and this is your answer: the equation of the line.
Answer:
Add the two x-coordinates and divide by 2 and the same thing for y-coordinates....takes two coordinates must be the ones that are the end points of the line
Answer:
10+10= 20/10= 2-0= 2+1000000000= 1000000002
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
The formula for area of a triangle is A = (1/2)bh,
For the first triangle we can leave it in general terms, so it's area is
A = (1/2)bh, depending on what b and h are, but it doesn't matter here...
The second triangle has base that is twice the other triangles base. Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is
A = (1/2)(2b)h, which simplifies to
A = bh
Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional
