Can u me with this brainliest available

Horizontal compression by factor 2 will do following.
After compression graph of the function is going to be closer to line of symmetry of the parabola. Values of y are not going to change, but values of x will be 2 times  closer to the the line of symmetry.

For our case , line symmetry x=2,
points are going to be 2 times closer to this  line.
1st point (4, -3) converts into (3,-3)
2nd point (-4,5) converts into (-1,5) 

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!
