2x + 5y = -4

Step-by-step explanation:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Explanation:

Let's use point slope form to get

y - y1 = m(x - x1)

y - y1 = -4(x - x1) plug in the given slope m = -4

y - 5 = -4(x - 2) plug in the given point (x1,y1) = (2,5)

Now we isolate y

y - 5 = -4(x - 2)

y - 5 = -4x + 8

y = -4x + 8 + 5

y = -4x + 13

This equation is in slope intercept form y = mx+b

m = -4 is the slope

b = 13 is the y intercept

To get this into standard form, we add 4x to both sides so that the x and y terms are on the left side

y = -4x+13

y+4x = 13

4x + y = 13 is the final answer

This is in standard form Ax+By = C where

A = 4

B = 1

C = 13

Let's check the answer. Plug in (x,y) = (2,5) to find that...

4x+y = 13

4*2 + 5 = 13

8 + 5 = 13

13 = 13

We get the same thing on both sides, so the last equation is true. This means the first equation is true when (x,y) = (2,5). This confirms the point (2,5) is on the line and helps confirm the answer.

the answer is d

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
