Answer:
1. d
2. 2
Step-by-step explanation:
if it's a negative it's opposite will be a positive and vice versa
The point-slope form:

The slope-intercept form:

The formula of a slope:

We have the points (1, -5) and (-3, -7). Substitute:

Rewrite to the slope-intercept form:
<em>use distributive property</em>
<em>subtract 7 from both sides</em>

An area of rectangle: a · b
a = 0.4 km
b = 0.07 km
a · b = 0.4 km · 0.07 km = 0.028 km²
The answer is P = 2(l+w) units.
This is because when you let the perimeter of the rectangle be P, the length of the rectangle be l and the width of the rectangle be w.
The information above can be expressed as the following equation,
P = 2l + 2w
You can then factorise out the common factor, 2.
P = 2(l+w)
Thus, the answer is P = 2(l+w) units.
