iVinArrow [24]

You find the y-intercept by substituting 0 for x:-

y = -2(0) + 7

so its the point (0, 7)

A 90 degree rotation takes the 0 to 7 and the 7 to 0.

So its the point (7 , 0)

Please give me an explanation too I need help Solve for y: 2x-y=3
harina [27]

Answer:

y = 2x -3

Step-by-step explanation:

to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
