how do you find the x and y intercepts of an equation? i forgot.
when y-int, x=0 and x-int, y=0
so to find both, you would set both x and y to 0?
you do it separately to find each intercept
To find the x-intercept of an equation, you set y = 0 and solve for x. The x-coordinate of the point where the equation intersects the x-axis is the x-intercept.
To find the y-intercept of an equation, you set x = 0 and solve for y. The y-coordinate of the point where the equation intersects the y-axis is the y-intercept.
Let's take an example equation: y = mx + b.
To find the x-intercept, we set y = 0 and solve for x:
0 = mx + b
mx = -b
x = -b/m
So, the x-intercept is the point (x, 0), where x = -b/m.
To find the y-intercept, we set x = 0 and solve for y:
y = m(0) + b
y = b
So, the y-intercept is the point (0, y), where y = b.
