Answer:
equation of a line:
y = mx+c
1) find the gradient, m



2) find y-intercept, c using coordinate (1,-4)
y = mx + c
-4 = 0(1) + c
c = -4
the equation of line:
y = mx+c
y = 0(x) + c
y = c
y = -4
Answer:
<em>2(x) + 2(x + 3) = 90 </em>
Step-by-step explanation:
Width: x inch.
Length: (x + 3) inch.
P = 2
+ 2
P = <em>2(x) + 2(x + 3) = 90</em>
2(x + 9)
2*x + 2*9
2x + 18 ← answer
