The answer to this is 90.
Answer:
yes, they are proportional
Step-by-step explanation:
A proportion is a relation that can be modeled by a straight line through the origin. The equation will have the form ...
y = kx
where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.
__
If you start with the equation relating distance, rate, and time:
d = rt
and you fix the time at 50 seconds, then the equation becomes ...
d = 50t
This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.
Answer: The equation in slope intercept form is
y = 2x/5 + 4/5
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
The given equation is expressed as
2x - 5y + 4 = 0
Adding 5y to the left hand side and the right hand side of the equation, it becomes,
2x - 5y + 5y + 4 = 5y
5y = 2x + 4
Dividing the left hand side and the right hand side of the equation by 5, it becomes,
5y/5 = 2x/5 + 4/5
y = 2x/5 + 4/5
If both are similar ratio of sides will be same
