Answer:
=
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 )
given
y + 2x = 2 ( subtract 2x from both sides )
y = - 2x + 2 ← in slope- intercept form
with slope m = - 2
given a line with slope m then the slope of a line perpendicular to it is
= -
= -

Answer:
Proportionality equation:
Linear equation:
Step-by-step explanation:
So the amount that Cameron earns = 7/hr
Hours = x
And total earned amount = y
So we can form an equation from this for the total amount:
But the question asks us for a proportionality equation so:
Proportionality constant = k
So we get the equation:
Answer:
The height is 14.3 km
Step-by-step explanation:
Given
--- angle of elevation
Required
Determine the height above the ground
The question is illustrated using the attached image.
To calculate the required height, we make use of:
Where AB represents the height and BC, the distance.
So:
Make AB the subject
--- approximated
