As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.
The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.
Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).
Answer:
The equation would be y = -3x - 9
Step-by-step explanation:
Since we have the slope of 1/3, we know the slope of a perpendicular line would be -3. This is because perpendicular lines have opposite and reciprocal slopes. We can then use this and the point to solve in point-slope form.
y - y1 = m(x - x1)
y - 3 = -3(x + 4)
y - 3 = -3x - 12
y = -3x - 9
Answer:
Step-by-step explanation:
(x1 , y1) (x2 , y2 )
these are two coordinates
the distance between them is
square root of [ (x2 minus x1) to the square plus ( y2 minus y1) to the square }
for u si square root of { -6-4) to the square + (3-3) to the square]
