Answer:
4
Step-by-step explanation:
<em>When rotating a point 90 degrees counterclockwise about the origin the point A(x,y) becomes A'(-y,x). </em>
Point C has coordinates of (4, 3)
New coordinates will be C'(-3, 4)
<u>So the answer is:</u>
y-coordinate of C' is 4
Answer:
Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope
b is the y-intercept (value of y when the value of x is equal to zero)
Let
step 1
Find the slope
In this problem the value of b is equal to the y-coordinate point A
so
step 2
Find the equation of the line
substitute the values
---->
therefore
the function rule is equal to
Answer:
its a
Step-by-step explanation:
Answer:
slope is 1/2 or 0.5
Step-by-step explanation:
ΔX = 7 – -5 = 12
ΔY = 9 – 3 = 6
