Aline passes through the point (-6,8) and has a slope of 4/3 .write an equation in point-slope form for this line

So we know that the x-coordinate is -6 and the y-coordinate is 8
We also know the slope/gradient, which is 
The formula for the equation of point-slope is as follows
y = mx + b
      ↑
m being the gradient
So plug in the information that we have
y₂ - y₁ = m(x₂ - x₁)
y - 8 =  ( x - (-6)) {- (-6) is + 6)
I am taking - 8 to the right hand side
(When you see subtraction, you do addition)
y =  + 8 + 8
y =    + 16 

That. you would have multiple
