find the y-intercept for: x+3y=7

At the point of y-intercept, the coordinate of x is 0. Therefore, let x = 0 and solve for y.

0+3y = 7

At the point of y-intercept, the coordinate of x is 0. Therefore, let x = 0 and solve for y.

0+3y = 7

yint = 7/3 <==Answer

There's only one right answer to a math problem and when you're right, you're right.

Confirmed Y of X=0 in this equation is 7/3 or 2 1/3

Arrange the equation in the slope-intercept format:

y = mx + b --------------- eq. 1 where b is the intercept.

Given: x+3y=7

Rearrange it: 3y=-x + 7

y= (-1/3)x + 7/3 --------------- eq. 2

Comparing eq. 1 and eq. 2, intercept is 7/3, or two and one third.
