Y=mx+c where m is the gradient.
If the equation is perpendicular is -
Use y-y1=m(x-x1)
and you should get
y+1=- (x+4)
4y+4=-3x-12
y=-<span></span>x - 16
If the equation is perpendicular is -
Use y-y1=m(x-x1)
and you should get
y+1=-
4y+4=-3x-12
y=-<span>
Answer:
Step-by-step explanation:
This is the answer because:
1) 185 equals to because 18% is equal to 0.18 which is
2) to it's lowest terms is
3) It's lowest terms is because 18/2 is 9 and 100/2 is 50
4) can't be simplified any further because 9 and 50 don't have any common factors
Hope this helps! :D
Answer:
The student is expected to spend <em>15.4 hours </em>doing homework
Step-by-step explanation:
The scattered plot shows there is a close correlation between the variables. A line of best fit will go through the 'center' of the points. Since we are not required to find an exact line, we'll draw it in red color as shown below
To know the equation of that line, we must take two clear points of it from the graph. We'll pick (28,4) and (4,25)
The equation of a line, given two points (a,b) and (c,d) is
Using the selected points
Simplifying and computing results, the equation is
Using that equation, we can predict how many hours the students will spend doing homework if they spend 15 hours watching TV
=15.4 hours
So the student is expected to spend 15.4 hours doing homework
