Question 147314: I am struggling with intercepts. Can you help me to find intercepts for x+y=56
and y=3x? These are examples of the problems I am trying to solve but am struggling with. Thank you.

You can put this solution on YOUR website! To find the y-intercept, plug substitute 0 for x and solve for y.
To find the x-intercept, plug substitute 0 for y and solve for x.
.
x+y=56
To find the y-intercept, plug substitute 0 for x and solve for y.
x+y=56
0+y=56
y = 56
therefore, the y-intercept is at (0,56)
.
To find the x-intercept, plug substitute 0 for y and solve for x.
x+y=56
x+0=56
x = 56
therefore, the x-intercept is at (56,0)
.
For:
y=3x
To find the y-intercept, plug substitute 0 for x and solve for y.
y=3x
y=3(0)
y = 0
therefore, the y-intercept is at (0,0)
.
To find the x-intercept, plug substitute 0 for y and solve for x.
y=3x
0=3x
0 = x
therefore, the x-intercept is at (0,0)
