If, for example, you had x on one side and x on the other, then subtracting x from both sides "disappears" x. If no other power of x shows up on either side, then your equation either has no solution or is always true.
(x,y)
sub given points and see if true
A, (0,-13)
x=0
y=-13
3(-13)=5(0)-13
-39=0-13
-39=-13
false (other user was just guessing)
B. (3,1)
x=3,
y=1
3(1)=5(3)-13
3=15-13
3=2
false
C. (7,7)
x=7
y=7
3(7)=5(7)-13
21=35-13
21=22
false
D. (-6,-1)
3(-1)=5(-6)-13
-3=-30-13
-3=-43
false
answer is none of them
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 5x -3. What is the point slope form of the equation for this line?
we have
This is the equation of the line in slope intercept form
where
the slope is 
the y-intercept is 
Remember that
The equation of the line in point-slope form is equal to
we have
substitute
The scale factor of DEFG to PQRS is: 3/8.
<h3>What is a Scale Factor?</h3>
- A scale factor of a dilation is the number by which the size of an original figure is changed to a new figure.
- Scale factor is ratio of corresponding side of new figure to original figure.
Thus:
DE corresponds to PQ.
PQRS is the new figure.
DE = 8; PQ = 3
Scale factor of DEFG to PQRS = PQ/DE
Scale factor = 3/8.
Thus, the scale factor of DEFG to PQRS is: 3/8.
