Answer:
slope = - 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 7 is in this form with slope m = 2
This line is perpendicular to the side it bisects.
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= -
Answer:
who ever line crosses the y-axis at -4.
Step-by-step explanation:
Given :
A freight elevator has a weight limit of 15,000 pounds.
Workers have loaded items weighing 2.6 tons onto the elevator.
To Find :
How many more pounds of freight can they load before reaching the weight limit.
Solution :
We know, 1 ton = 2000 pounds.
So, 2.6 ton = 2.6 × 2000 = 5200 pounds.
Now, number of pounds of freight can be loaded before reaching the weight limit is :
N = 15000 - 5200 pounds
N = 9800 pounds
