How do you find the x and y intercept of #2x+y=10#?
y = (0,10) x = (5,0)
Use the y = mx + b formula for finding the y intercept.
2x - 2x + y = -2x + 10 this gives
y = -2x + 10
b = the beginning the starting point or the y intercept.
so 10 is the y value of the y intercept.
y intercept = ( 0, 10 )
The slope ( m ) = -2 Think m = mountain slope the angle of the mountain.
Solve for x when y is zero
0 = -2x + 10 The x intercept will be the value when y = 0
solve for x start by subtracting 10 from both sides.
0 -10 = -2x = + 10 - 10 this gives
-10 = -2x divide both sides by -2
5 = x
so the value of the x intercept is ( 5,0 )
