Question

The graph of the equation y=-2x+5 will intersect the y-axis when y equals what value?

Answer 1

do you mean y = -2x - 5 as your equation? :)

Answer 2

sorry i ment y=-2x+5

Answer 3

An axis is intersected when the other parameter is zero.

Answer 4

i think of these as "Y" dont we begin "5"

Answer 5

so ur line starts at +5

Answer 6

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
