Answer:
y=-1/4x+1
Step-by-step explanation:
so here are my steps after plugging in the numbers:
y-3=-1/4(x+8)
y-3=-1/4x-2
y=-1/4x+1
9514 1404 393
Answer:
D. 36 units
Step-by-step explanation:
Using the distance formula, we find the length of AB to be ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15
The line BC is horizontal, so its length is the difference of the x-coordinates:
BC = 7 -(-2) = 9
The line AC is vertical, so its length is the difference of the y-coordinates:
AC = 9 -(-3) = 12
The sum of the lengths of the sides of the triangle is ...
P = 15 + 9 + 12 = 36
The perimeter is 36 units.
Answer: The simplified expression is: " -2y + 19 " .
________________________________
Explanation:
Simplify this given expression: " 10 - 6y + 4y + 9 " .
Start with combining the "like terms:
+ 10 + 9 = + 19 ;
- 6y + 4y = - 2y ;
Now write the simplified expression:
" -2y + 19 " .
Note that the variables come first; in order of degrees, then the numbers, if any.
Hope this helps!
Best of luck to you in the "Brainly community" and in your future academic pursuits!

Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
