Write the equation 12 − y = 2x − 5 in slope-intercept form. What are the slope and y-intercept?

such an equation is usually written y=mx+b ("y=mx+c"bin the UK).

Calculate the slope:

slope is defined as the change in "y" divided by the change in "x". We note that for x=0, the value of is 17.000 and for x= 2.000 the value of "y" is 13.000. So for a change 2.000 in x ( The change in "x" is sometimes referred to as "RUN") We got a change of 13.000-17.000= -4.000 in "y". (The change in "y" is sometimes referred to as"RISE" and the slope is m= RISE/RUN)

1. slope= -2

2. x- intercept= 17/2=8.50000

3. y- intercept= 17/1=17.00000

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
