Slope intercept form: y= mx +b
Parallel lines= same slope
Find slope of this line first:
2x + 3y =8
Subtract 2x from left side and add it to right side.
3y = -2x + 8
Divide by 3
Y= -2x/3 +8/3
slope= -2x/3
Y= mx + b —-} b is y intercept which is unknown and m is slope
Plug in -2/3x for slope.
Y= -2/3x +b
To find y intercept plug in point (-2, 3)
Y= -2/3x+b
3= -2/3(-2) +b
3 = 4/3+b
3-4/3 =b
5/3 =b
Y= -2/3x +5/3 is new equation
<em><u>Complete Question:</u></em>
The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?
<em><u>Answer:</u></em>
The numerator of fraction is -360
<em><u>Solution:</u></em>
Given that,
<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>
We have to solve the equation for "n"
Rearrange the equation
Thus the numerator of the fraction is -360
<span>4x – 5y = –18 (1st)
3x + 2y = –2 (2nd)
Multiply 1st equation by 2 and 2nd equation by 5
</span>4x – 5y = –18 (1st) (mul. 2)
3x + 2y = –2 (2nd) (mul. 5)
8x - 10y = - 36
15x + 10y = - 10

23x = - 46
x = -2
3x + 2y = –2
3(-2) + 2y = –2
-6 + 2y = -2
2y = 4
y = 2

Answer:
(0, 2)
Step-by-step explanation:
When segment AB has midpoint M, the coordinates of M are ...
M = (A+B)/2
Solving for B, we find ...
2M = A+B
2M -A = B
Filling in the given values for the midpoint (M) and the one end (A), we have ...
B = 2(3, 7/2) -(6, 5) = (6 -6, 7 -5) = (0, 2)
The other endpoint of the segment is (0, 2).
