Answer:
A. y = 2x -9
B. y = -1/2x +1
Step-by-step explanation:
The given line is in slope-intercept form
y = mx + b
where m is the slope. For your given line, the slope is 2.
A. A parallel line will have the same slope. It is convenient to start with a point-slope form of the equation for the line:
y = m(x -h) +k . . . . . for slope m through point (h, k)
You want the equation of the line through (4, -1) with slope 2, so its equation is ...
y = 2(x -4) -1
Simplifying to slope-intercept form, this becomes ...
y = 2x -8 -1
y = 2x -9
___
B. A perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line. That slope is ...
m = -1/2
As above, the point-slope form of the perpendicular line is ...
y = -1/2(x -4) -1
y = -1/2x +1 . . . . . after simplification
Answer:
Example: 2/3 + 4/6 + 5/12
Step-by-step explanation:
First find the least common multiple.
2*
2, 4, 6,8, 10. 12, 14, 16, 18, 20
6*
6, 12, 18, 24, 30, 36, 42, 48
12*
12, 24, 36, 48, 60, 74
the least common multiple all three denominators share is -12-
*Evaluate*
2/3 = 8/12
2 times 4 is 8
3 times 4 is 12
*whatever you do to the top you do to the bottom*
