Answer:
y=-3/2x+4
Step-by-step explanation:
The slope or m is -3/2 and the y-intercept or b is 4.
Hope this helped :)
Answer:
d
Step-by-step explanation:
Solution by substitution method
y=7x+8
∴y-7x=8
and y=x+20
∴y-x=20
Suppose,
-7x+y=8→(1)
and -x+y=20→(2)
Taking equation (1), we have
-7x+y=8
⇒y=7x+8→(3)
Putting y=7x+8 in equation (2), we get
-x + 7x + 8 = 20
6x = 20-8
6x = 12
x= 12 / 6
x = 2
substitute for x in equation (3)
y = 7(x) + 8
y = 7(2) + 8
y = 22
Answer:
or
Step-by-step explanation:
step 1
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are the same
we have

therefore
The slope m of the line parallel to the given line is

step 2
Find the equation of the line in point slope form

we have


substitute
----> equation of the line in point slope form
step 3
Find the equation of the line in slope intercept form

we have
Isolate the variable y
