Triangle ABC has been rotated 90° to create triangle DEF. Write the equation, in slope-intercept form, of the side of triangle ABC that is perpendicular to segment EF. Please show work.

y=1x+1

Step-by-step explanation:

The side of triangle ABC which is perpendicular to EF is BC.

y=mx+c

m= (y2-y1)÷(x2-x1)

take any 2 pts that lie on the line

e.g: 0,1 and 1,2

now substitute the two points that you chose

m=(2-1)÷(1-0)

=(1)/(1)

=1

slope is 1

now y=1x+x

substitute any point at x and y to get c value

e.g: 0,1

1=0+c

c=1

so the slope intercept form is y=1x+1
