Answer:
x = 8
Step-by-step explanation:
Answer:
Step-by-step explanation:
L : y = -4x + 3
with a slope of -4.
Any line perpendicular to L will have a slope m such that
m ( -4) = -1, or m = 1/4
Any line perpendicular to L passing through point (a,b) will therefore have the form
P : (y-b) = (x-a)/4
When (a,b) = (8,1) as given, then substitute in P to get
P : (y-1) = (x-8)/4
y=x/4 -2 + 1
y = x/4 -1
F(x)=1/3-1/21x
0=1/3-1/21x multiply both side by 21
0=7-x
X=7
Answer:
m=3, y-int=-1
Step-by-step explanation:
y-3x=-1, reorganize this into y=mx+b by moving -3x to the right side.
y=3x-1, remember that in y=mx+b, m=slope, which is 3 as you can see easily.
The y-intercept is when x=0. So plug this into y=3(0)-1, which is just y=-1.
Answer:
y = 7x - 2
Step-by-step explanation:
12 - (-16) / 2 - (-2)
28/4
7
Replace variables
EX. (2, 12)
12 = 7 (2) +b
12 = 14 +b
-2 = b
y = 7x -2
EX.
y = 7 (-2) -2
y = -14 -2
y = -16
