What expressions are equivalent to q+p+q+p+q

Kipish [7]

You can resolve all of them.
so the first one would be 3q+2p
that second 2p+3q
the third 2p+2q+q which equals 2p+3q

they all end up as the same thing so both are equivalent

a line passes through the point (4 –6) and has a slope of -<img src="https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D" id="TexFormu

Answer:

$y = \frac{5}{4}x - 1$

Step-by-step explanation:

A line that passes through the point (4,-6) has a slope of 5/-4. Which of the following gives the equation of the line?

With the slope of 5/-4, and the ordered pair (4,-6) :

let m = 5/-4 (slope),

x1 = 4

y1 = -6

We can use those given values into the point-slope formula:

y - y1 = m(x - x1)

Plugging in those values will give you the answer:

y - (-6) = $\frac{5}{-4}$ (x - 4)

Distribute $\frac{5}{-4}$ into the terms inside the parenthesis:

y + 6 = $\frac{ 5}{-4}x$ + 5

Subtract 6 from both sides to isolate y:

y + 6 - 6 = $-\frac{ 5}{4}x$ +5 - 6

The equation of the line in slope-intercept form is:

$y = -\frac{ 5}{4}x - 1$
