From the equation of line: y = mx + c

Given, y = -1/4x + 2 , The slope ( m ) = -1/4, intercept = 2

For the second one, y = x, the slope ( m ) = 1 and intercept is 0

To find the coordinate for the first equation, we need to

1.) find y when x = o

= y = -1/4( 0 ) + 2

= y = 0 + 2

y = 2

2.) Find x when y = 0

= 0 = -1/4x + 2

= 4 x 0 = -x + 2

= 0 = -x + 2

= -x = -2

= x = 2

Thus, the coordinate for the first question y = -1/4x + 2 is ( 0,2 ) ( 2,0 )

To find the coordinate for the second equation, y=x. we ...

1.) find y when x = 0

= y = 0

2.) find x when y = 0

= 0 = x

so x = 0

Thus, the coordinate for the second equation y=x is ( 0,0 ) ( 0,0 )
