The common rule is (x - 1, y + 3) can be used to describe the translation.
Step-by-step explanation:
Step 1:
The point J (-3, -4) becomes (-4, -1).
In order to write the rule for translation from J to , we subtract the x coordinate of J from
and subtract the y coordinate of J from
.
The x coordinate
The y coordinate
Step 2:
So from the calculations, we get that the x coordinate is subtracted by 1 i.e. and the y coordinate is increased by 3 i.e.
.
So the common rule is (x - 1, y + 3).
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x + 9 ← is in slope- intercept form
with slope m = - 4
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, hence
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (4, 5) into the partial equation
5 = 1 + c ⇒ c = 5 - 1 = 4
y = x + 4 ← equation of perpendicular line → C
