Answer:
6x - y + 7 = 0
Step-by-step explanation:
To find the equation of line passing through a point and slope of same line is given, we use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (6, 43)
and m is a slope of line passing through (x₁, y₁) which is equal to 6.
Substituting all values in above formula. We get,
⇒ y - 43 = 6 ( x ₋ 6)
⇒ y - 43 = 6x - 36
⇒ 6x - y + 7 = 0
which is required equation.
Answer:
for four copies the cost is $72
Step-by-step explanation:
52 + 5a = 24 + 12a
28 + 5a = 12a
28 = 7a
a = 4
52 + 20 = 72
for four copies the cost is $72
Based on the graph, the amplitude is 0.5. You can determine this number as well if you look at the x axis. Hopefully I helped you.
