Linear Equations : Slope-Intercept Equations Quiz
Quiz
*Theme/Title:
Slope-Intercept Equations
* Description/Instructions
The standard form of linear equations (Ax + By = C) can be manipulated into the slope-intercept form. The S-I equation is y = mx + b, where "m" is the slope, and "b" is the y-intercept. Y must be isolated in order to do this.
Example: 2x + y = 4
Subtract 2x from both sides: 2x - 2x + y = 4 - 2x
y = -2x + 4
Sometimes you have to divide by the coefficient to isolate y.
Example: 9x + 3y = 12
Subtract 9x from both sides: 9x - 9x + 3y = 12 - 9x
3y = -9x + 12
Divide both sides by 3: y = -3x + 4
For each problem, identify the correct slope-intercept form. If the equation is written properly, select "DNC" for "do not change". Select the best answer from the choices.
