Definitions and Formats of Systems of Linear Equations

How would I wrote 3y - 12x = 15 in

y = mx + b form?

• y = 4x + 5

• y = 3x + 5

• y = 2x + 3

• y = 5x - 4

What form must an equation be in for you to graph it?

• y = mx + b

• ax^2 + bx + c = 0

• y = a sin(bx + c)

• z = x + y

Convert the equation 2y = 8x - 6 into y = mx + b form.

• y = 2x - 1

• y = 4x - 3

• y = 3x + 2

• y = 5x - 4

When graphing an equation in the formula y = mx + b, which letter would be the starting point of my graph?

• m

• b

• x

• c

How would you write the following equation in y = mx + b form?
6x + 3y = 12

• y = -2x + 4

• y = 2x + 4

• y = -2x - 4

• y = 3x + 2

In y = mx + b, the letter b represents:

• the slope of the line

• the y-intercept

• the x-intercept

• the constant term

What is the slope of the line represented by the equation y = -3x + 7?

• -1

• 0

• -3

• 2

In the equation y = 5x + 2, what is the y-intercept?

• 0

• 1

• 2

• 3

In y = mx + b, the m represents:

• the slope of a line

• the y-intercept of a line

• the length of the line

• the angle of the line

What formula helps you find the slope of a line?

• Change in y over Change in x

• Change in x over Change in y

• y = mx + b

• y = x^2
