Answer:

Graph D

Step-by-step explanation:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

What is the y-intercept of the line perpendicular to the line y = four thirdsx + 1 that includes the point (4, 1)?
s2008m [1.1K]

Answer:

(C)4

Step-by-step explanation:

Given the line: y=\dfrac43 x+1

The gradient of the line, m=\dfrac43

A line perpendicular to the given line will have a gradient, m=-\dfrac34 (by definition of perpendicularity).

Therefore, a perpendicular line that passes through the point (4,1) is:

y-y_1=m(x-x_1)\\y-1=-\dfrac34(x-4)\\y-1=-\dfrac34x+3\\y=-\dfrac34x+3+1\\y=-\dfrac34x+4

Comparing with the slope-intercept form y=mx+x, the slope of the perpendicular line, b=4.
