Question

What is the equation of the line that passes through the points (0, -4) and (2, 8)?



y= 6x- 4
y= 6x+ 4
y= 4x+ 6
y= -4x+ 6

Answer 1

first find the slope then use point slope form
\[\Large m=\frac{8-(-4)}{2-0}=\frac{12}{2}=6\]
now it is upto you use any point from the above two and use this formula (point slope form)
\[\Large y-y_{0}=m(x-x_{0})\]
m is already found and (x0,y0) is any point you use to use

Answer 2

@miadeex can you do this now?

Answer 3

any point you choose to use !

Answer 4

i got b

Answer 5

ok it should be
a

Answer 6

remember it is -4 when using the above equation !

Answer 7

Use slope formula to calculate the slope and then apply point-slope form.....
slope= y2-y1/x2-x1 Which gives.... 6
now, put any of the point... in the point slope form.... U will get...... y-8=6(x-2) then ...y= 6x-4 Option A
