The answer is:
y= -2.5x + 4
You have to do -2.5 times the x value
Then add 4 and you should get the correct number for each y value.
If x +23 = 9, then, x = 9-23.
So x = -14
Answer:
y = 1x - 3
Step-by-step explanation:
Note that the given line has slope +1.
Any line parallel to this line must also have slope +1.
Apply the slope-intercept form y = mx + b:
Inserting -3 for y, 0 for x and 1 for m, we get the y-intercept
-3 = 1(0) + b, which tells us that b = -3 and that the desired equation is
y = 1x - 3
