Answer:
x=9
Step-by-step explanation:
2x+10=28
2x=18
x=9
Answer:
parallel
Step-by-step explanation:
The "work" is to recognize that both equations describe horizontal lines. All horizontal lines on the Cartesian coordinate grid are parallel.
_____
<em>Additional comment</em>
y = constant . . . . . a horizontal line (y=0 is the x-axis)
x = constant . . . . . a vertical line (x=0 is the y-axis)
__
If you wanted to go to the trouble, you could compare the equation ...
y = constant
to the slope-intercept form ...
y = mx +b
Your comparison would note that m=0. That is, the slope is zero, so the line is horizontal. All lines with the same (zero) slope are parallel.
