Step-by-step explanation:
2.5x+8y=200
We want to get this in slope intercept form so we will solve for y
Subtract 2.5x from each side
2.5x-2.5x+8y=-2.5x +200
8y = -2.5x +200
Now divide by 8 on both sides
8y/8 = -2.5x/8 + 200/8
y = -.3125x +25
The y intercept is 25, so plot a point there
-.3125 = -5/16
Go down 5 and to the right 16 and plot a point. Connect the two points to make a line.

Step-by-step explanation:
2x2−3x−4=0
For this equation: a=2, b=-3, c=-4
2x2+−3x+−4=0
Step 1: Use quadratic formula with a=2, b=-3, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−3)±√(−3)2−4(2)(−4)
2(2)
x=
3±√41
