Question

I dont understand the problem

Answer 1

equation of a line:

y = mx+c

1) find the gradient, m

`m = (y2 - y1)/(x2 - x1)`

`m = ( - 4 - ( - 4))/( - 10 - 1)`

`m = 0`

2) find y-intercept, c using coordinate (1,-4)

y = mx + c

-4 = 0(1) + c

c = -4

the equation of line:

y = mx+c

y = 0(x) + c

y = c

y = -4
