Answer:
The slope is 9, and the y-intercept is -2.
Step-by-step explanation:
the slope-intercept form is y=mx+b
The slope is m and the y-intercept is -2
So the slope is 9, and the y-intercept is -2.
y=9x-2
Hope this helps!
Answer:
B C D
Step-by-step explanation:
Given that △XYZ is mapped to △X'Y'Z' using the rules (x, y)→(x+5, y−3) followed by (x, y)→(−x, −y) .
We know that (x,y) => (x+h,y+k) type operation represents translation so rule (x, y)→(x+5, y−3) will cause translation.
We know that (x,y) => (-x,-y) type operation represents rotation about origin so rule (x, y)→(−x, −y) will cause rotation.
So combining both results and comparing with given choices. we find that only 1st choice "△XYZ is congruent to △X'Y'Z' because the rules represent a translation followed by a rotation, which is a sequence of rigid motions."
is correct.
The answer would be in a coordinate plane between quadrant 2 and 3.
Answer:
D, A
Step-by-step explanation:
a line segment has two endpoints and a length that is finite or can be measured.
a line goes in both directions infinitely; cannot be measured
a ray has one endpoint and travels in 1 direction infinitely; cannot be measured
