How do you find the x and y intercepts for #x + y = 10 #?

Answer 1

Eli Assouline

Put the equation into the intercept forms
y = mx + b and

x + y = 10 subtract x from both sides

# x - x + y = -x +10 #

y = -1x + 10 The y line crossing at ( 0 , + 10 )

m the slope is -1 putting -1 in the equation and solving for y

gives y = -10

The y intercept is +10 the x intercept is -10

#"x-intercept "=10," y-intercept "=10#

#"To find the intercepts, that is where the graph crosses"# #"the x and y axes"#

#• " let x = 0, in the equation for y-intercept"#

#• " let y = 0, in the equation for x-intercept"#

To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
