Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.

Write an equation in​ point-slope form of the line that passes through the given​ points, then write the equation in​ slope-inte
frosja888 [35]

As we go from (-6,6) to (9,1), x increases by 15 and y decreases by 5.  Thus, the slope of this line is m = rise / run = -5/15, or m = -1/3.

Point-slope form:  y-6 = (-1/3)(x+6), using data from (-6,6).  

Slope-intercept form:  starting with y = mx + b, substit. -6 for x, 6 for y and -1/3 for m:

6 = (-1/3)(-6) + b, or

6 = 2 + b.  Then b = 4, and the equation in slope-intercept form is

y = (-1/3)x + 4.

If a = b + 2, then (b - a)⁴ = ?
Hatshy [7]
Use substitution.

anywhere you see "a" , than you would plug in b + 2 in for it so....

(b - (b + 2)^4 

now take the negative sign and distribute it "+"

so b - b is 0, than 0 - (-2) is -2.

so what is (-2)^4     ????? it would become positive 16
