Does anybody understand writing equations in slope intercept form?

Mathematics

Hello!

Explanation: The y-intercept is the point on a graph at which the graph crosses the y-axis.

Slope-Intercept Form: y=mx+b

Let m represent the slope.

(0¹,b¹) (x²,y²)

m=rise/run=y-b/x-0

x(m)=y-b/x)x

mx=y-b

+b    +b

mx+b=y

And switch sides of an equation.

y=mx+b

Hope this helps!

slope intercept form

y=mx+b

where m is the slope and b is the y intercept

if we change from point slope form

y-y1 = m(x-x1)

we distribute

y-y1 = mx -x*x1

then add y1 to each side

y = mx -x*x1+y1


remember x and y are variables and should stay in the equation

m,x1,y1 are numbers from the problem

you may have to calculate the slope (m) from the formula

m = (y2-y1)/(x2-x1)  from two points on the line

Aneli [31]

Answer:

Deductive reasoning

Step-by-step explanation:

Here, we want to know the kind of reasoning the statement is.

In this question, the kind of reasoning is deductive

In the deductive reasoning type, we go from general cases to specific cases

It is just like saying the reason why there will be hurricanes in the tropics this fall is because there is an hurricane every fall

So we have gone from a general case to give a specific case

Solve x 2 + 9x + 8 = 0 by completing the square. What are the solutions?
Sindrei [870]

So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: x^2+x+8x+8=0

Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: x(x+1)+8(x+1)=0

Now you can rewrite the equation as (x+8)(x+1)=0

Now using zero product property, solve for x:

x+8=0\\ x=-8\\ \\ x+1=0\\ x=-1

<u>In short, the solutions are {-1,-8}, or C.</u>

Elodia [21]
Hello! So $10,000 is the annual budget. 50% of the budget is spent on food, 25% of it is spent on beverages, 10% is spent on decorations, and the remaining 15% is spent on staff for the party. That's because 50 + 25 + 10 is 85. 100 - 85 is 15. Let's multiply the budget by 15% to find the amount spent on staff. 10,000 * 15% (0.15) is 1,500. There. $1,500 were spent on staff for the party.
