Answer:
y = - 1/4 + 4
Step-by-step explanation:
y = 4x - 7
Slope = 4
Slope of the perpendicular line = -1/4
Point (8,2)
(b) y-intercept: 2 - (-1/4)(8)
= 2 + 2 = 4
5% fail
so 100-5=95% are left
percent means parts out of 100
95% of 100 is

times 100=95
95 students are left assuming that the 5% that fail fail within 12 months
First, set up the equation using the point-slope formula (y-y1)=m(x-x1).
y1=-4 x1=-3 m=-7/2
(y+4)=-7/2(x+3)
Second, distribute -7/2.
(y+4)=(-7/2)x - 21/2
Third, subtract 4 from both sides.
(y+4)=(-7/2)x - 21/2
-4 -4
______________
y=(-7/2)x - 29/2
Answer:
Zero
Step-by-step explanation:
Undefined is a Vertical Line, remember the 2 U's Undefined is Up and Down. Zero, is straight across.
