Answer :
1. y = 2x + 3
2. y = x^2 + 5x - 3
3. y = -2x^2 + 7x – 4
are the 3 examples of equation with y intercept.
1. The first example is a linear equation, which has the form of y = mx + b, where m is the slope and b is the y-intercept.
2. The second example is a quadratic equation, with the form of y = ax^2 + bx + c, where a, b, and c are coefficients.
3. The third example is also a quadratic equation, with the form of y = ax^2 + bx + c, where a, b, and c are coefficients.
