How do you find the x and y intercepts for x + y = 10 x+y=10?
2 Answers
Put the equation into the intercept forms
y = mx + b and
Explanation:
x + y = 10 subtract x from both sides
# 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

• " let x = 0, in the equation for y-intercept"∙ let x = 0, in the equation for y-intercept
• " let y = 0, in the equation for x-intercept"∙ let y = 0, in the equation for x-intercept 6
