Answer:
The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.
Step-by-step explanation:
1) perimeter = 36 ft
explanation:
p=2l+2w
p=2(8)+2(10)
p=16+20
p=36
area = 80 ft^2
explanation
a=l*w
a=8 ft* 10 ft
a=80 ft^2
2) perimeter = 28
explanation:
p=2l+2w
p=2(7)+2(7)
p=14+14
p=28
area = 49 in^2
explanation:
a=l*w
a=7in*7in
a=49 in^2
