Answer:
y = -3/4x + 5/4
Step-by-step explanation:
Points: (7, -4) and ( -1, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2+4)/(-1-7)
m=6/(-8)
m= -3/4
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = -3/4(x - 7)
y + 4 = -3/4x + 21/4
y = -3/4x + 5/4
The given polynomial is:
The first step to factor taking out the GCF is to write each term in prime factored form, so:
The second step is to identify the factors common in all terms, they are: 3xcxd
Finally, factor out the GCF:
The answer is above

Answer:
x - 5y = 22
Step-by-step explanation:
Step 1: rewrite the equation of the given line in to slope-intercept form by solving for y
x = 5y - 9
-5y = -x - 9 (subtract 5y and x from both sides)
y = x/5 + 9/5 (divide both side by -5)
Step 2: Our line is parallel to this line, so it has the same slope, but a different y-intercept, so set up the equation...
y = x/5 + b
We are given a point (x, y) of (2, -4), so plug that in and solve for b.
-4 = 2/5 + b
-4 - 2/5 = b (subtract 2/5 from both sides to isolate b)
-20/5 - 2/5 = b
-22/5 = b (simplify)
So the equation of our line is y = x/5 - 22/5
Step 3: Standard form is ax + by = c, where a is a positive integer
subtract x/5 from both sides...
-x/5 + y = - 22/5
multiply by -5 so x becomes a positive integer
x - 5y = 22
