Answer: y = 2/3x + 41/3
Step-by-step explanation:
First convert the equation into slope-intercept
3x + 6y = 4y - 4
-4y -4y
3x + 2y = -4
-3x -3x
2y = -3x - 4
y = -3/2x - 2
Perpendicular lines have a negative reciprocal for their slopes.
The negative reciprocal of -3/2 is 2/3
Now using the slope 2/3 you will use the formula y =mx +b and input the slope, and the x and y coordinates of the given point, (-10,7), to solve for the y-intercept.
7 = 2/3(-10) + b
7 = -20/ 3 + b
+ 20/3 + 20/3
b = 20/3 + 21/3 = 41/3
Since the the y-intercept is 41/3 then the equation will be , y = 2/3x + 41/3
180-90=3x
90=3x
X=30
90+x+y=180
90+30+y=180
120+y=180
Y=60
4/10 would be 2/5 in simplest form.
I hope this helps! (:
Answer:
D. 4 x -2 - 7/8
Step-by-step explanation:
4 x -2 7/8
2 7/8 can be separated into 2 pieces 2 +7/8
4x - (2+7/8)
Distribute the minus sign
4x - 2 -7/8
