The slope-intercept form of a line is:
y = mx + b
Where m is the slope and b is the y-intercept.
Two lines having slopes <em>m1</em> and <em>m2</em> are perpendicular if
m1 * m2 = -1
We are given the equation of one line:
It's required to find the equation of another line that is perpendicular to it. We have m1 = 1/3, let's find the other slope:
The slope of the required line is -3. Now we use the point through which the line passes (-2, 2).
We use the point-slope form of the line:
y - k = m( x - h)
Where (h,k) = (-2, 2) is the point. Substituting:
Operating:
It’s a because you have to calculate and do the formal slope
3x ≥3.0 - 2.4
3x ≥ 0.6
x ≥ 0.6/3
x ≥ 0.2 is your answer
Answer:
266.7 ft
Step-by-step explanation:
If.... 14 inches = 200 ft
Then the height of the house;
; (14/10.5) × 200
; 1.33333 × 200
Height of the house = 266.7 ft
