What is the equation of a line passing through (-6, 5) and having a slope of 1/3 ? A. B. C. D. y = 3x + 7

stepan [7]

Answer:

y = 1/3 x + 7

Step-by-step explanation:

Given; the line is passing through, (-6,5) and the slope is 1/3

We can get its equation;

We would take, a point (x,y) and the given point (-6,5)

Therefore; Since slope = Δy/Δx

Then;

(5-y)/ (-6-x) = 1/3

3(5-y) = -6 -x

15 - 3y = -6 - x

we get;

3y = 6 + x + 15

3y = x + 21

Therefore;

<u>y = 1/3 x + 7</u>

Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen i

trapecia [35]

Answer:

$[H^{+} ]= 10^{-pH}$

Step-by-step explanation:

To solve this question it is important to remember logarithm rules. That is:

$a^{y} =x\\\\logx_{a} = y$

$pH = -log[H^{+}]\\\\-pH = log_{10}[H^{+} ]\\\\H^{+}] = 10^{-pH}\\$
