x - 8y = 4; turn the equation in the slope-intercept form, y = mx + b, where b is the y-intercept. x - 8y = 4x - x - 8y = -x + 4-8y = -x + 4 divide by -8 to both sidesy = x/8 - 1/2 Thus, the y-intercept is -1/2.
80 = 80/1.
I beileive that the absolute value of -20 is 20 because if you do the absolute value it seems to turn out as the positive form of itself in other words, if you take -10 and find the absolute value, it is 10 and if you take 60 and find the absolute value it equals 60
yes turn the 6x4 sideways and they arevequal tada and ur the smart one ha
Say you had 750+-15. You would do 15 divided by 750 equals .02. Then multiply be 100 to turn it into a percentage and you get 2%.
It is: y = -0.4x+1 when in slope intercept form.
If: 20x+80y = 0 Then: 80y = -20x And: y = -0.25x So the slope is -0.25 and it has no y intercept
Equation
Subtract x from both sides:- y = -x +90
8x-5y = -40 -5y = -8x-40 y = 1.6x+8 which is now in slope intercept form
3x-6y=12; subtract 12 & add 6y to both sides 3x-12=6y; divide by 6 (1/2)x-2=y; re-write y=(1/2)x-2 slope intercept form
Slope intercept form is y=mx+b To convert 6x-3y-9=0 into this form, we must first isolate y. We do this by adding 3y to both sides. Now we have 3y=6x-9 To simplify this, we divide both sides by 3. The answer is now y=2x-3
slopeintercept equations are used to find the slope and intercept (obviously lol) they are set up like this y=mx+b m is the slope and b is the y-intercept lets say you have an equation like... 2x + y = 5 (now minus 2x from both sides) 2x - 2x + y = 5 - 2x (simplify) y = 5 - 2x just use algebra to turn the standard form to slope intercept form
Y = - 2X + 8 Just read it off the function, aY = mX + C - 2 = m(slope) 8 = Y intercept You can also zero out the variables in turn
2x-4y = 8 2x = 4y + 8 2x - 8 = 4y 2x/4 - 8/4 = y (1/2)x - 2 = y So, y = (1/2)x - 2, where 1/2 is the slope and -2 is the y-intercept :)
3x + y = 7 First, turn the equation into the slope-intercept form, y = mx + b, where m is the slope of the graph that that equation represents (solve for y).3x + y = 7 subtract 3x to both sidesy = -3x + 7So you clearly see that the slope is -3.
x - 8y = 4; turn the equation in the slope-intercept form, y = mx + b, where b is the y-intercept. x - 8y = 4x - x - 8y = -x + 4-8y = -x + 4 divide by -8 to both sidesy = x/8 - 1/2 Thus, the y-intercept is -1/2.
