do you mean y = -2x - 5 as your equation? :)
sorry i ment y=-2x+5
An axis is intersected when the other parameter is zero.
Not the answer you are looking for? Search for more explanations.
i think of these as "Y" dont we begin "5"
so ur line starts at +5
oh okay :)
So we have the equation y = -2x + 5
To find when it will intersect the y-axis, it meant when will it cut the y-axis?
Note the slope-intercept form:
y = mx + b
where m = slope and b = y-intercept :)
So what will the "b" be in your equation y = -2x + 5 ?
@GrinningShadow sometimes it's better to explain the method so they can learn a method instead of just getting the answer
are you still confused?
Another method to find the y-intercept is that... we know the y-intercept occurs when x = 0.
Therefore for your equation y = -2x + 5.
Plug in x = 0 (this means where you see "x" in the equation, replace it with 0) and we get:
y = -2(0) + 5
y = ?
^This will be your y-intercept
