I have the equation Y equals -1x plus b and the starting coordinates 60 70 how do i find the y- intercept the line is going from right to left on the X axis?

In the equation [ y = - 1x + b ], the y-intercept is 'b'.
Take the point you know ... (60, 70) ... and plug it into the equation:
y = - x + b
70 = - 60 + b
Add 60 to each side:
130 = b
And there you have it!
The y-intercept is 130 .

What are the coordinates of the y-intercept in the graph of the equation x plus y equals negative 9?
The y intercept will be where the x-coordinate is zero, so set x=0 in the equation and you have: 0 + y = -9, or y = -9. Coordinate (0,-9)
What is the x intercept in this equation 5x-2y equals 20?
5x - 2y = 20The x-intercept of a line is the point where its y-value is 0. When y=0, we get 5x = 20, or x=4. This means the coordinates of the x-intercept on this line are (4,0).
What is the equation of the line if x intercept equals 4 and y intercept equals 4?
y=-x+4
