Answer:

Study study study study study

Step-by-step explanation:

Studying is boring. I don't like it, but never put it off to the last minute, and DO NOT SPEND 2 HOURS READING MATERIAL!!! You need study breaks and just reading won't help very much. Make flashcards with different colors, and have someone quiz you(It is scientifically proven to help you remember).

Answer:

$y = -2x +3\\\rule{150}{0.5}\\\text{Slope: -2}\\\text{Y-Intercept: 3}$

Step-by-step explanation:

We would have to convert the standard equation into slope-intercept form.

======================================

<h3>Converting the equation into Slope-Intercept Form:</h3>

$8x + 4y = 12\\\rule{150}{0.5}\\8x - 8x + 4y = 12-8x\\\\4y = 12-8x\\\\4y = -8x + 12 \leftarrow \text{I switched the order on the right side.}\\\\\frac{4y=-8x+12}{4}\\\\\boxed{y = -2x + 3}$

======================================

<h3>Identifying the Slope and Y-Intercept:</h3>

General slope-intercept form is:

$y=mx + b\\\rule{150}{0.5}\\\text{m - Slope}\\\text{b - Y-Intercept}$

In the equation $y = -2x + 3$ , '-2' would be the slope since it is in 'm's place, and '3' would be the y-intercept since it's in 'b's place.

Therefore:

$\text{In } y=-2x+3\text{...}\\\rule{150}{0.5}\\\text{Slope: -2}\\\text{Y-Intercept: 3}$

======================================

Hope this helps!

What is a linear equation in math?

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

$\frac{3^{2} * 3^{-5} }{4^{2} } = \frac{3^{-3} }{4^{-2} }$
