Step-by-step explanation:

Answer:
a) line 3 because the coefficient of the term 5x, the slope is the greatest slope.
b) line 1 and 4 are parallel because they have the same slope: 2
c) line 1 with line 2 and line 4 with line 2 are perpendicular lines because their slopes are reciprocals negative.
d) line three crosses the y line at point 11
Step-by-step explanation:
Line 1. y = 2x - 3
Line 2: y = -2x + 3
Line 3: y = 5x + 11
Line 4: y = 2x - 10
Line 5: y = 1/2x - 5
Answer:
The answer is 429/40 (<u>in fraction form</u>), but if you want the <u>actual numbers</u> the answer is 10.725
Step-by-step explanation:
All you have to do is multiply the numbers (I multiplied them in a calculator), and you will get the answer.
