iona) The error is in dividing both sides of the equation by 3
b) the correct answer is 4x + 3y = 12
Explanation:The given equation: 3y = -4x + 12
To represent in standard form, it must be in the form:
Ax + By = C
rewitiing 3y = -4x + 12 in standard form
3y + 4x = 12
4x + 3y = 12
The student answer: y = -4/3 x + 4
From the above, we can see the student divided both sides of the equation by the coefficient of y. Both sides were divided by 3.
This procedure is only done when finding the slope of an equation and the coeffiecient of y is not 1.
a) The error is in dividing both sides of the equation by 3
b) the correct answer is 4x + 3y = 12
the x intercept: y = 0
4x + 3y = 12
4x + 3(0
