Yea. The text book is either wrong or it knows something that we don't. Like as to why they would need to have two more feet. You're right though
Given data:
The given equation of line is y=x/4+5.
The given y-intercept is (0,c)=(0,-3).
The standard equation of line is,
y=mx+c
Compare the given equation with the above expression.
m=1/4
The expression for the slope which is perpendicular to the given line.

The equation of the line which is perpendicular to the given line is,

Thus, the line which is perpendicular to the given line is y=-4x-3.
Answer:
7a ( 1,1)
7b ∅ or no solution
Step-by-step explanation:
The solution to the system is where the two functions intersect
For 7a. The parabola and the line intersect at (1,1)
For 7b The parabola and the line do not intersect so there is no solution
A. 6(k + s)
It's the distributive property.
Is there a picture for the graph?
