Hey can you me posted picture of question

The standard equation of a parabola by definition is given by:
 x = ay2 + by + c
 Where,
 a, b, c are the coefficients of the equation
 y is the independent variable
 x it is the dependent variable.
 
 The standard equation of the parabola is:
 x = ay2 + by + c
 option D

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
