Answer:
Step-by-step explanation:
Both equations should be in slop-intercept form (y=mx+b)
So add -2x to -6. Your equation should look like this
y=2x-6
In y=mx+b
b will fall on y-axis
mx is rise/run
So in the first equation plot -6 on y axis and go up 2 and over 1(because 2x is equivalent to 2/1 x)
In the second equation plot -1 on the y axis. Then go up 1 and over 3 from that point.
238 students are enrolled in the 7th grade class this year
<u>Solution: </u>
Given that
Percentage decrease in number of students enrolled in 7th grade = 15%
Number of students enrolled last year = 280
Need to determine number of students enrolled in 7th grade this year.
Lets assume number of students enrolled this year = x
<em>Percentage decrease in enrollment </em>= (Number of student enrolled last year – Number of students enrolled this year) whole divided by number of students enrolled last year multiplied by 100
Hence number of students enrolled this year = 238.
