Answer:
y = 5x - 4
Step-by-step explanation:
Step 1: Write known variables
m = 5
y = 5x + b
Step 2: Find <em>b</em>
6 = 5(2) + b
6 = 10 + b
b = -4
Step 3: Rewrite equation
y = 5x - 4
Answer:
I think D
Step-by-step explanation:
Hi there!
To find the perpendicular slope you need to flip the fraction and change the sign. So 1/2=2/1 and tge original slope was positive, so the slope is -2. Now you sub in the point (-7,-4) in for x and y in the formula y=mx+b and solve for b (sub in 2 for m as well)
Y=mx+b
-4=-2*-7+b
-4=14+b
-4-14=b
B=-18
The equation is y=-2x-18
Hope this helps!
Answer:
Step-by-step explanation:
Equation
L = a + (n - 1)*d
Givens
L = 55
a = 13
n =8
Solution
55 = 13 + (8 - 1)*d Combine
55 = 13 + 7d Subtract 13 from both sides
55 - 13 = 7d
42 = 7d Divide by 7
d = 6
