Answer:
A, C and F.
Explanation:
Equation of a line:
The equation of a line has two formats:

Slope-intercept format, in which m is the slope and b is the y-intercept(which is the value of x when y = 0).
And in point-slope form:

In which (x(0),y(0)) is the point and m is the slope.
Slope:
When we have two points on a line, the slope is given by the change in y divided by the change in x. We have points (-2,4), (1,-2). So
Change in y: -2 - 4 = -6
Change in x: 1 - (-2) = 1 + 2 = 3. So
m = -6/3 = -2.
Equation in slope-intercept:
The y-intercept is y = 0, so b = 0. The equation in slope-intercept formula is:
, so option A is marked.
Equation if point-slope:
Point (-2,4) means that
. So



So option C is correct.
Point (1,-2) means that
. So



So option F is correct.
Answer:
Options A, C and F are correct.
