if the equation is 2x+y=8 then the slope is -2

In order to find the slope, you need to get y by itself.Follow the equation: y = mx + bm = slope-48 = 2x - 8ySubtract 2x from both sides of the equation.-2x - 48 = (2x - 2x) - 8y(I find it easier to have y first in the equation, but either way is fine.)-8y = -2x - 48Divide every number by -8.-8y/-8 = (-2x/-8) + (-48/-8)y = 1/4x + 6y = mx + bm = 1/4
The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.
2x + 3y = 8 Usually you would solve for y to get the equation in Slope Intercept Form. (y = mx + b) Where (m) is the slope and (b) is the y intercept of the graph. First get the y by itself by subtracting 2x and getting it to the side with the 8. You now have this... 3y = -2x + 8 Now Isolate the variable (y) by dividing by 3. You now have this... y = - 2/3 + 8/3 Now since you have this in Slope Intercept Form, you know - 2/3 is the slope of the line and 8/3, or 2 2/3, is the y intercept on your graph.
Slope-Intercept Form: y = -2x +1
