Question 344025: Rewrite each of the following linear equations to express y as a function of x. Determine the slope and y-intercept for the gragh of the solution set of each equation.
A. 2x+y=6 B. 8x-5y=20 C. -4x-3y=15 Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! NEED TO KNOW:
STANDARD FORM OF A LINEAR EQUATION IS y = mx + b WHERE "m" is the slope and b is the y-intercept (x=0). (Written as a fuction of x) f(x) = mx + b
Rewrite:
2x+y=6
y or f(x) = -2x+6 (slope is -2 and y-intercept is 6)
8x-5y=20
8x-20 =5y
y or f(x)= 8/5x-4 (slope is 8/5 and y-intercept is -4)
-4x-3y=15
-4x-15 = 3y
y or f(x)= -4/3x -5 (slope is -4/3 and y-intercept is -5)
