Awalking path across a park is represented by the equation y equals negative 2x -7. a new path will be built perpendicular to this path. the pats will intersect at the point -2, -3. identify the equation that represents the new path

So we are given an initial equation of: .

We are told that a new path is going to be perpendicular to this line. So to find a slope that is perpendicular to a line, we take the slope of the known line (in this case 2) and we flip it and change the sign. So since this slope is essentially , we are going to flip it to make it and change the sign to make it .

So now we know that the slope of the perpendicular line is , we can start a new equation for this line:

We are also told that the path will intersect at (-2,-3) - this is a solution to the two lines. So to find b in this new equation, let's plug in the x and y values found in the point:

Then solve for b:

So then we plug in our value for b and leave x and y:

So this equation now represents the new path.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
