Write the linear equation y= -3x + 5 in the form ax+by=c

• -3x-y=5

• -3x+y=5

• 3x+y=5

• 3x-y=5

Answer

• The student incorrectly subtracted the x- coordinates in the denominator.

• The student did not simplify the fraction to its lowest terms.

• The student reversed the order of the coordinates when calculating the slope.

• A. The student incorrectly subtracted the y coordinates in the numerator.

Why is x+y=5 a linear equation in two variables?

• All of the above

• Because it can be written in the form y= mx + c, where m and c are constants.

• Because its graph is a straight line.

• Because it has two variables, x and y, and the highest power of each variable is 1.
