Her sister could be about four or five
Centre?/Origin? (at the middle point) and Radius (on the line)
a) find the slope of the line using the given points.
Slope: 9 - -3/6-0 then slope is 12/6 which is 2
Then using formula: y = mx+b
-3 = 2(0) + b
b = -3
The equation is: y = 2x -3
B. Slope of a perpendicular is -reciprocal of first line. So here the slope will be -1/2
y = mx + b is used again
2 = -1/2(0) + b
b = 2
The equation is: y = -1/2x +2
Answer:
Step-by-step explanation:
The solution is the set of points where all the equations intersect. If there is no such point, there is no solution.
For example,
y = 8
y = 6
These are parallel lines with no points in common.
Answer:
Step-by-step explanation:
If the whole length of DEF is given as 7, and segment DE is 2, then segment EF is 7 - 2 = 5
