Find the y-intercept of each line defined below and compare their values.

Y - intercept of equation of-line A is y = 1.

Y - intercept of equation of-line B is y = -2.

Step-by-step explanation:

Given:

For Iine A:

For line B:

x = -2  then y = 2

x = -1  then y = 0

x = 0  then y = -2

x = 1  then y = -4

To Find:

Y- intercepts of Line A and Line B.

Solution:

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.

Y-intercept mean x coordinate will be 0

Therefore Put x = 0 in Line A we get

Y - intercept of equation of-line A is y = 1.

For line B

See where x coordinate is 0 ,Therefore we have,

y = -2

Y - intercept of equation of-line B is y = -2.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
