Question

Help I don't know the answer (Pics included)

Answer 1

first calculate the equation of the line

Answer 2

I have no idea what that means. I had a "self-teach" teacher,
so I learned nothing 1st semester.

Answer 3

substitute two points, for instance the points of intersection with x and y axis in the general equation of line passing through two different points:
(y - y_0)(x_1 - x_0) = (y_1 - y_0)(x - x_0).

Answer 4

the line intersects x axis in point (4,0)=(x_0,y_0) substitute the coordinates in equation of the line then do the same with point of y axis intersection (x_1,y_1)

Answer 5

or you can substitute these points in slope- intercept form(y=mx+c), and solve the system of linear equations

Answer 6

for example: the points that line passing through are; A(1,2) and B(3,6)
then 2=m*1+b
and 6=m*3 +b
you will find m and b, then just put them into equation y=mx+b
in this case its : y=2x

Answer 7

Have you got the line equation?

Answer 8

I don't know

Answer 9

what is the point of intercection with y axis?

Answer 10

it's the point P, right?
