Answer:
y= x
Step-by-step explanation:
Given the two points:
- Origin (x1, y1) = (0, 0)
- The point (x2, y2) = (5, 9)
Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).
=>Time, x the independent variable,and distance is the dependent variable.
We have the standard form of a linear equation is:
y= mx + b where a is the slope
We know that, the slope of the function is:
m =
In this situatuon, m =
=> y= x + b(1)
The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:
0 = *0 + b
<=> b = 0
So our equation that the graph represents is: y= x
Answer: False
Step-by-step explanation:
The ancient Greeks required a straightedge and a compass to construct a perpendicular bisector for a given line segment.
They made perpendicular bisector by using following steps.
Let given a line segment XY, then to construct the perpendicular bisector.
Step 1)Draw a circle centered at X and passing through point Y.
Step2)Draw a circle centered at Y and passing through point B.
Step3)The two circles intersect at two points (above and below of line segment XY). Draw the line through these two points. This line is the perpendicular bisector to XY.
