1.what is the y-intercept of the plane whose equation is 4x + 5y – z = 20? (5, 0, 0) (0, 5, 0) (0, 4, 0) (0, 0, 4) 2.which equation has intercepts at x(1, 0, 0), y(0, –1, 0), and z(0, 0, 2)? 3x – 2y + 6z = 12 4x – 4y + z = 4 x – y + 2z = 4 2x – 2y + z = 2 5.is attached below

Option c and

Option d

Step-by-step explanation:

Given is a plane

To find y intercept

In the y axis x=0=z

Substitute to get

Hence point is (0,4,0)

2) When x intercept = 1, y int =-1 and z int =2 we have in intercept form the plane

is the right one

Option d

step-by-step explanation:

vertical=18cm horizontal=18cm hypotenuse=25.5
