Answer (<u>assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula 
and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:
So, the slope is 
.
2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.
3) Now, write the equation of the line in slope-intercept form using the 
format. The number in place of 
represents the slope, so substitute in its place. The number in place of 
represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:
A1 or just a as it is in the equations is just the initial term of the sequence. In this case a1=1
r is the common ratio which is that constant ratio found by dividing any term by the term preceding it...
In this case r=3/1=9/3=27/9=etc=3
So a1=1 and r=3, C. is your answer.
50.5 and 53.5
104-3=101 divided by 2=50.5 50.5+3 equals 53.5. 50.5+53.5=104
no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor
Because both 100 and 140 share a common factor of 20
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio
