Set x to =0 then do the equation
10 = 2(0) + 5y
10 = 5y
10/5 5y/5
y = 2 The y intercept is 2
Do the same for y
10 = 2x + 5(0)
10 = 2x
10/2 2x/2
x = 5 The x intercept is 5

At x=0 the equation is 5y=10. Dividing both sides of this by 5 shows that y=10/5=2 is the y-intercept. That is, y=2 at x=0.
At y=0 the equation is 2x=10. Dividing both sides of this by 2 shows that x=10/2=5 is the x-intercept. That is, x=5 at y=0.

The x-intercept is when the curve crosses the x-axis. The formula for the x-axis is y=0. Put y=0 into the equation to get 2x=10, meaning the x-intercept is 5.

y = 2 - 2x/5 so for y intercept = 2
x = 5 - 5y/2 so for x intercept = 5

To Find each, you set the other variable to zero and solve the equations. i.e.
Y intercept:
2x +5y = 10
2(0) + 5y = 10
5y=10
y = 2
X intercept
2x + 5y = 10
2x +5(0) = 10
2x = 10
x = 5
Therefore, the X intercept is 5 and the Y intercept is 2.

making use of simultanoeus equation, addind the two equtions, we've 2x +5y = 20 ------------(a million) -2x + 5y = 10--------------(2) --------------------- o + 10y = 30 10y= 30 y= 3 Substituting y=3 in any of the euqations, say equation (2) we've - 2x + 5y = 10 ...........and y = 3 -2x + 5 (3) = 10 -2x + 15 =10 -2x = 10 - 15 -2x = - 5 x = 5/2 for this reason, x = 5/2 and y = 3

to find the x-intercept, set y=0 and solve for x,
to find the y-intercept, set x=0 and solve for y
2x+5*0=10
2x=10
x=5
x-intercept = 5
2*0+5y=10
5y=10
y=2
y-intercept = 2
