Answer:
5x +6y -90 = 0
Step-by-step explanation:
The perpendicular line will have the x- and y-coefficients swapped, and one of them negated. The constant will be chosen so the equation is satisfied at the given point.
5x +6y = 5(6) +6(10) = 90
The equation of the perpendicular line in general form is ...
5x +6y -90 = 0
Answer:
the ratio for this blueprint is 1:20
Step-by-step explanation:
The scale on a blueprint indicates that ½ " equals 10 feet
The ratio is in the form of a:b
Here from the given information
the value of 'a' is 1/2 and the value of b is 10
so the ratio a:b becomes
Multiply both sides of the ratio by 2 to remove fraction
so the ratio for this blueprint is 1:20
