Question

find the equation of a straight line passing through the point (1,1)with y intercept-4​

Answer 1

Answer:

3X+y=4

Step-by-step explanation:

required equation is

x/a+y/b=1

keepingx=y=1and b=4

we get a

Answer 2

Answer:

y = -3x + 4

Step-by-step explanation:

as we know that

y intercept = 4. i.e. point which locate at y axis has coordinates ( 0,4 )

point P = (1,1)

slope = y2 - y1 / X2 - X1

m = 4- 1 / 0- 1

m = -3

now ,

y = mx + c

:. c = y intercept

so

y = -3x + 4
