All that you know is that it goes through that one point.

^And if you have the equation of the line in slope-intercept form (y = mx + b) the "b" is the y-intercept. For example, if a y-intercept was at (0, -8), then the equation would be y = mx - 8, but you'd need more information to determine "m."

If you mean 2x+5y = -10 then the y intercept is -2

The answer is 4

-4.6

Assuming that you meant "x - 4y = 20", the x-intercept is x=20, and the y-intercept is y=-5.

y = {slope}x + {y intercept}

The y-intercept of that line is the point (0, 21).

3 + 4

As for example if the slope is 3 and the y intercept is 6 then the equation is: y=3x+6

Slope = 0, intercept = 3

The y intercept is when x =0, so the answer is -6

The equation of a line in slope-intercept form is given by y = mx + b, where "m" represents the slope of the line and "b" represents the y-intercept.

If you're given an existing point and the slope of the line, then yes - the y-intercept depends on the slope.

The y- intercept of a line is where the line crosses the y axis. The x- intercept is where the line crosses the x axis.

If you mean: y = 4x-6 then the slope is 4 and the y intercept is -6

If you mean 2x+5y = -10 then the y intercept is -2

If you mean: y = 5x+16 then the y intercept is 16 and the slope is 5
