Standard Form of Linear Equations

Which of the following is the right form for Standard Form of a linear equation?

• $y=mx+b$

• $m=\frac{y_2-y_1}{x_2-x_1}$

• $y-y_1=m\left(x-x_1\right)$

• $Ax+By=C$

 $x\ =\ 7$  What is the A, B and C value of the following equation?

• A = 1, B = 0, C = 7

• A = 0, B = 1, C = 7

• A = 1. B = 0, C = 8

• A = 0, B = 1, C = 8

What is the equation of the vertical line that passes through the point (5,-2)

• x = 5

• x = -2

• y = 5

• y = -2

What is the equation of the horizontal line that passes through the point (5,-2)

• x = 5

• x = -2

• y = 5

• y = -2

 What is the x and y-intercepts of the following equation?

 $-3x\ +\ 4y\ =\ -24$ 

• x-intercept: -8, y-intercept: 6

• x-intercept: 8, y-intercept: -6

• x-intercept: 6, y-intercept: -8

• x-intercept: -6, y-intercept: 8

What is the x and y-intercept of the following linear equation. PUT THE ANSWER AS A POINT!!!!

 $\frac{1}{2}x-\frac{1}{3}y=2$  

Put it in this format;
(#,#) and (#,#)

using the word "and," with the x-intercept listed first and the y-intercept listed second. Notice a space between the parentheses and the word "and."

Pencils are $0.10 each and pens are $0.25 each. If Raj wants to buy a combination of pencils and pens, but he only has $50 to spend, which equation can help him to determine the x, amount of pencils he can buy and the y, amount of pens he can buy?

• 0.25x + 0.10y = 50

• 0.25x - 0.10y = 50

• 0.10x + 0.25y = 50

• 0.10x - 0.25y = 50

Pencils are $0.10 each and pens are $0.25 each. Raj wants to buy a combination of pencils and pens, but he only has $50 to spend. The equation 0.10x + 0.25y = 50 models this scenario.

What does the point (0, 200) represent in this scenario?
