Consider the line y = 1/4 - 5/4 x Slope of a parallel line Slope of a perpendicular line

gladu [14]

Answer:

parallel line slop2 = -5/4

perpendicular line slope = 4/5

Step-by-step explanation:

If 2 lines are parallel, they will have equal slopes.

Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4

If 2 lines are perpendicular, their slopes are negative reciprocals of each other. So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5

Part A: A graph passes through the points (0, 2), (2,6), and (3. 12). Does this graph represent a linear

allsm [11]

Answer:

The function given is non-linear.

Step-by-step explanation:

The slope between (0, 2) and (2,6):

$\frac{6-2}{2-0}=\frac{4}{2}=\boxed{2}$

The slope between (2,6), and (3, 12):

$\frac{12-6}{3-2}=\frac{6}{1}=\boxed{6}$

Since the slopes are not equal to each other, the function is non-linear. A linear function's slope must stay consistent.

Hope this helps.
