Answer:
There are 180 students at the school
Step-by-step explanation:
If 10% of the students like the color purple, then 100-10 = 90% do not like the color purple.
Students * percentage that do not like = students that do not like
students * 90% = 162
Change to decimal form
students *.90 = 162
Divide each side by .90
students *.90/.90 = 162/.90
students = 180
There are 180 students at the school
This is a horizontal line at y = -3. If you want to find it mathematically, you could find the slope (y2-y1)/(x2-x1) and you would get 0 over 5, so you know the slope is zero. Pick either point and substitute the numbers into point-slope formula. I went with (3, -3) and got (y - -3) = 0(x-3). The right side is just 0, and if you subtract three from both sides to isolate y, you get the equation y = -3.
