Question

What is an equation of the line that passes through the points (5, -4) and (-5, 4)

Answer 1

The equation is y = -0.8x + 0

The graph for it is shown below :)

Answer 2

y=-0.8x

Explanation:

slope=(y2-y1)/(x2-x1)

=(4-(-4))/(-5-5)

=8/-10= -0.8

y=-0.8x+b

4=-0.8(-5)+b

4=4+b

b=0

y=-0.8x
