### Which equations have the same slope as y 3x 4?

**Parallel lines** have the same slope. The equation of a line is typically written as y = mx + b where m is the slope and b is the y-intercept. You have the equation y = 3x + 4 where the slope, m, is 3.

For that reason, what is the meaning of 3 times 4?

top: 2:4 time indicates two beats per measure. bottom: 3:4 time indicates **three beats per measure**.

Hence, what is the solution of the equation 3x 4? The solution of the equation 3x-4**=1-2xis___________**

In a general, how do you solve for x?

What is the slope of 3x 4?

Algebra Examples Using the slope-intercept form, the slope is **âˆ’3** .

y=3x. This equation is in **slope intercept form**, and can be rewritten as: y=3x+0 , where 3 is the slope and "0" is the y-intercept. Determine a few points on the line by choosing values for x and solve for y . Points.

When multiplying mentally, people generally like **to do the bigger or important quantities first**. This gives an estimate of the value expected. Such an approach is front end or left to right multiplication. Students using this method multiply the tens before the ones and hundreds before the tens and so on.

Answer: 1/3 of 15 is **5**.

3 x âˆ’ 4 = 1 3x-4=1 3xâˆ’4=1. Add 4 to both sides. Simplify 1 + 4 1+4 1+4 to 5. Divide both sides by 3.

Answer: 2 x + **3** = 7 2x+3=7 2x+3=7. Subtract 3 from both sides. Simplify 7 âˆ’ 3 7-3 7âˆ’3 to 4.

Hence, by solving the value of variable x in the linear equation \[ax + b = 0\] is \[\dfrac{{ - b}}{a}\] . Hence we have solved for x and obtained the solution. So, the correct answer is â€œ **\[x = \dfrac{{ - b}}{a}\] â€**.

more ... The letter "x" is often used in algebra to mean a value that is not yet known. It is called **a "variable" or sometimes an "unknown"**. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

2 Answers By Expert Tutors The equation of the line in question is: y = 3x - 4 , which is in slope-intercept form. Note that the general form of the slope-intercept equation is: **y = mx + b** , where m is the slope of the line (rise/run) and b is the y-intercept of the line (the point where x=0).

The **slope equals the rise divided by the run: Slope =riserun Slope = rise run** . You can determine the slope of a line from its graph by looking at the rise and run.

y=3 will be a straight horizontal line; y=3x will be a **straight inclined line**.

Using the slope-intercept form, the y-intercept is **0** .

For easy and fast mental math calculations, you should **add or subtract from the left to the right**. For example, adding 340 + 215 will quickly give you the answer: 555. In case of carrying forward numbers, just add it to the digit before them, like 340 + 285 = 625.

The Atlantic Canada Mathematics Curriculum supports the acquisition of these skills through the development of thinking strategies across grade levels. Mental math refers to **fact learning, mental computation, and computational estimation**.
