The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept ... of the line, so the equation will be \(y ...

The x-coordinate of any point on the y-axis has the value of 0 and substituting \(x = 0\) into the equation \(y = ax^2 + bx + c\) gives \(y = c\). a) The constant term is -2, so the y-intercept is ...
