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:
Abel has 30
Bob has 19
Step-by-step explanation:
Abel = a
Bob = b
a + b = 49
a = b + 11
Substitute:
2b + 11 = 49
2b = 38
b = 19
a = 30
