Answer:
y - 7 = -2(x - 4)
Step-by-step explanation:
We are asked to write the equation of a line in point slope form
Step 1 : find slope
We are given the slope to be -2
Slope m = -2
Step 2: substitute m into point slope form
y - y_1 = m( x - x_1)
y - y_1 = -2 ( x - x _1)
Step 3: substitute the point into the equation
y - y_1 = -2( x - x _1)
( 4 , 7)
x_1 = 4
y_1 = 7
y - 7 = -2( x - 4)
We don't need to open the bracket because we are asked to write the equation in a point slope form
Answer:
W value 56 ft
Step-by-step explanation:
The formula for the perimeter of a rectangle is
P = 2L + 2W
Here P = 156 ft = 2(22 ft) + 2W, or
78 ft = 22 ft + W
This yields the W value 56 ft
