Y - intercept is the value of y - coordinates of the point where the line intersects the y - axis, that is :

• $0$

Y - intercept = 0

Answer 2

Answer:

Let's find slope first

Take 2points

• (1,-2)
• (0,0)

$\\ \sf\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}$

$\\ \sf\longmapsto m=\dfrac{0+2}{0-1}$

$\\ \sf\longmapsto m= \dfrac{2}{-1}$

$\\ \sf\longmapsto m=-2$

Equation of the line

$\\ \sf\longmapsto y=mx+b$

Put values

$\\ \sf\longmapsto -2=-2(1)+b$

$\\ \sf\longmapsto b=-2+2$

$\\ \sf\longmapsto b=0$

y-intercept is 0
