Plug 1 in for x to get 7y=3(1)-7
7y=-4
y=-4/7
Answer:
y=-3x+7
Step-by-step explanation:
slope intercept from is y=mx+b where m is slope and b is the intercept. so far we can plug in what we know. -8=y; 5=x; and -3=m.
(-8)=(-3)(5)+b. now solve for b which would give us b=7. now we plug in m and b int y=mx+b which gives us
y=-3x+7
Answer:
b = - 2, b = 4
Step-by-step explanation:
Using the distance formula
d = 
with (x₁, y₁ ) = M(3, 1) and (x₂, y₂ ) = N(- 1, b)
d = 
= 
= 
Then
= 5 ( square both sides )
16 + (b - 1)² = 25 ( subtract 16 from both sides )
(b - 1)² = 9 ( take square root of both sides )
b - 1 = ±
= ± 3 ( add 1 to both sides )
b = 1 ± 3
Then
b = 1 - 3 = - 2 or b = 1 + 3 = 4
The answer is 7x athats it
