1. Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. To answer this question, plug in the values they have given you.

y=mx+b
y=1/4x-5

2. To write an equation in slope-intercept form when given two points, use m=y2-y1/x2-x1

Remember: in an ordered pair, x comes first then y.

Plug the y- and x-values in. So, y2=6, y1=2 and x2=-2, x1=9

6-(-)2/-2-9= - 4/11.

The slope of your next equation would be m= - 4/11

Which expression fits this description?
madam [21]

Answer:

The expression that fits the description is ;

(8a + b)/4

Step-by-step explanation:

Here, we want to find the expression that fits the given description;

We are told that the expression is a sum of two terms

The first term is 2 * a = 2a

The second term is the quotient ( result of division) of b and 4 = b/4

So the term we are looking for is;

2a + b/4 = (8a + b)/4

Which number is greater and by how much? a decreased by 50% and then increased by 50% of the result
zaharov [31]

Answer:

Let's assume the number is 100 now it is increased by 50% that means

100+ (50/100)*100

100+50=150

Now it is decreased by 25% that means

150- (25/100)*150

150–37.5=112.5

Total percentage increase ={(112.5–100)/100}*100

=12.5%
