Answer: x + 7y = 12
Explanation:
The question is: "I<span>ndicate in standard form the equation of the line passing through the given points. E(-2, 2), F(5, 1)"
</span>
1) The standard form of the equation of the line passing through two points is:
Ax + By = C
2) You can find the equation of al line given two points in a two stages process:
i) Find the slope:
slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7
ii) set the point slope equation:
y - y₁ = m [x - x₁]
y - 1 = (-1/7) (x - 5) ⇒ 7 ( y - 1) = - (x - 5)
⇒ 7y - 7 = - x + 5 ⇒ x + 7y = 5 + 7
⇒ x + 7y = 12

Answer:
x = (n-h)/j
Step-by-step explanation:
n = jx + h
Subtract h from each side
n-h = jx+h-h
n-h = jx
Divide by j
(n-h)/j = jx/j
(n-h)/j = x
N is the number of the Tshirt
c is the cost
the relationship between the cost and the number of the Tshirt is:
12n+3=c
so if 1 is the number of the tshirt so the cost is
12.1+3=12+3=15
if n=2 c=12.2+3=24+3=27
and etc.....
