Write the equation of a line that is perpendicular to the line y=4 and passes through point (-1, 1)
1 answer:
Answer:
x = - 1
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 4
A perpendicular line is a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 1, 1) with an x- coordinate of - 1, thus
The equation of the perpendicular line is x = - 1

Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways
