The equation of line is:
Further explanation:
The general form of point-slope equation is:
It is given that m = 1/2
Putting in the value of m
We have to find the value of b so putting the value of x and y
(x,y) = (7,-6)
Putting the values of b and m in general form

Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)
It will be
.. y = -4/3x +c . . . . . for some value of c
_____
The slope of the perpendicular line will be the negative reciprocal of the slope of the given line, which is 3/4.
We know 623.1 because 40 times 12 = 480 add with the area of the triangle which is 1/2 * 12 *5 = 30, and the circle A=πr2=π·62≈113.09734, and add them up to equal 623.1 square feet
