Question

find the y-intercept of the line with the slope m=a and contain the point (1,2)

Answer 1

Answer:

• According to question slope is "a"

and point given as (1,2)

• according to slope point form equation of line given as (y-y1)=m(x-x1)
• we have to find y intercept it means on that point x =0
• so by putting x=0 and ( x1 , y1 =1,2) and m=a in the normal slope point form we get as fallows

y-2=a(0-1)

i.e y= -a+2

so the y intercept will be -a+2
