Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)
point slope formula:
(y₂ - y₁) = m(x₂ - x₁)
Then we substitute any of the two set of coordinates to find c, the y - intercept.
So the line has a gradient of m and y - intercept of c
Answer:
(3x^2+ 2x+ 1) - (x^2- 3x+ 4)
Correct Simplification:
3x^2+ 2x +1 - x^2 + 3x - 4
2x^2 + 5x - 3
Ans C
He did not multiply the - for -3x
Hope it helps you.
