For a line in the form:

In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:

Now, two lines are perpendiculars if the slopes satisfy the following equation:

So, for the line we want the slope is:

Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:

The equation of the line is y = 5x - 7
921÷ 2 = 460.5
which means the remainder is 1
So; the answer is 1
Answer: x=-1/2
Step-by-step explanation:
2/3x+1/2=1/6
Subtract the 1/2
2/3x=-1/3
Divide by 2/3
x=-1/2
nearest 1000: 920,000
nearest 100: 919,800
nearest 10 (you said 100 but I think you mean 10): 919,830
