x-intercept


To find the x-intercept, plug in y=0 and solve for x


3x%2By=-7 Start with the given equation.


3x%2B0=-7 Plug in y=0.


3x=-7 Simplify.


x=%28-7%29%2F%283%29 Divide both sides by 3 to isolate x.


So the x-intercept is .


------------------------------------------


y-intercept


To find the y-intercept, plug in x=0 and solve for y


3x%2By=-7 Start with the given equation.


3%280%29%2By=-7 Plug in x=0.


0%2By=-7 Multiply 3 and 0 to get 0.


y=-7 Simplify.


So the y-intercept is .

find the intercepts for the equation
3x+y=-7
x-intercept:
Let y = 0, then x = -7/3
------------------------------
y-intercept:
Let x = 0, then y = -7
