Answer:
-1
Step-by-step explanation:
4x=-4
X = - 1
That's itt
Answer:
y=3x-1
Step-by-step explanation:
start at (-1,-4) and go up 6 and over 2, thats your slope or m.
the y intercept is -1
Answer:
62.5
Step-by-step explanation:
2cm = 25mi
1cm = 12.5 (25/2)
5cm is 2 + 2 + 1
2 + 2 + 1 = 25 + 25 + 12.5 = 62.5
Answer:
y=-2x+3
Step-by-step explanation:
equation for slope is y=mx+b
the slope is -2 so that equals m
(0,3) is the y-intercept
y=b
3 is the y value making it substitute b making the equation y=-2x+3
The distance formula is:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
To use it, you need to have two points on a line that will look like this:
(x1, y1) and (x2 , y2)
Then you just plug it in, and you get your answer.
