Answer:
y = -6, perpendicular
Step-by-step explanation:
You can use the points to find the slope of the line:

Then, using point-slope form, choose one set of coordinates to use for y1 and x1:




Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.
Answer:
2/45
Step-by-step explanation:
0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as:
. Multiplying the two fractions results in 4/90 which can be simplified to 2/45.
