Answer:
The value of this expression is -35.
Step-by-step explanation:
Let's use the order of operations (PEMDAS), to solve this problem.

In conclusion, the value of this expression is -35. Hope this helped :D
Step-by-step explanation:
7x + 3x + 90= 180
10x= 180-90
10x= 90
x= 90/10
x=10
First Find slope by using


Now use point Slope form to find the equation of the line (y-y₁)=m(x-x₁)
(y-6)=

(x-2)
y-6=

y=

is your equation
A point doesn't have a slope. A line has. You need to find the slope of the line that these 2 points are on. The slope is
(the difference of the 'y' values) divided by (the difference of the 'x' values)
That appears to be zero. It's a horizontal line.
