Answer:
m=2 or y=2x+1
Step-by-step explanation:
first use the y2-y1/x2-x1 formula and then use y=mx+b formula
plug in 3 for y2 and 1 for y1
plug in 1 for x2 and 0 for x1
so ur slope is 2
_______________
for y=mx+b *extra info ig if u need it just incase*
i usually use the first point for this but u can use any one u want
plug in 0 for x
plug in 1 for y
and plug in 2 for m
1=2(0)+b
2*0=0
1=0+b
subtract o on both sides
1=b and b is ur y-intercept
y=2x+1
hope this helps
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. To see this process in action, check out this tutorial!

Answer:
The ratio of AC/CB=1/3
Step-by-step explanation:
We use the section formula:
We substitute the point A(-1.5,0) and B(4.5,8).
We plug in the points to get:
This is supposed to be equal to: (0,2).
We can equate, corresponding coordinates to find m and n.
This implies that:
Therefore the ratio is m:n=1:3
The first part of the second line, she left the -5 there. The correct work and solution should be this:
5(2x-1)-3x=5x+9
<span><span>7x</span>−5</span>=<span><span>5x</span>+<span>9
</span></span>2x-5=9
2x=14
x=7
