<span>y-intercept when x = 0
</span>so
y = -7x + 1
y = -7(0) +1
y = 1
Answer:
Step-by-step explanation:
Givens
Length = a
Width = a + 3
Formulas
P = 2L + 2w
Area = L * w
Solution
Perimeter
P = 2L + 2w
P = 2*a + 2(a + 3) Remove the Brackets
p = 2a + 2a + 6 Combine
<u><em>P = 4a + 6</em></u>
Area
Area = L * w
Area = a (a + 3)
<u><em>Area = a^2 + 3a</em></u>
Answer:
true
Step-by-step explanation:
Y = -4x + 3
Because, it has the same slope (-4) as the slope of y = -4x + 8
