Question

Find the equation of the lines: with a y-intercept of 4 and passes through the point (-1,3)

Answer 1

Answer is y=x+4

Explanation:

Answer 2

equation is 4x-4y= -16

Explanation:

b = 4

x = -1

y = 3

so

x/a + y/b = 1

or, -1/a + 3/4 = 1

or, (-4 + 3a) = 4a

or, -4 = 4a - 3a

so, a = -4

now

x/a + y/b = 1

or, x/-4 + y/4 = 1

or, 4x-4y = -16

so

equation : 4x-4y = -16
