Change to percent form = .7 *100% = 70%
Answer:
y
Step-by-step explanation:
Just use the formula...,
; y - y(coordinate) = slope × [ x - x(coordinate)]
; where we firstly have to calculate the slope...,
; (8 - 2)/(4 - 6) = -3
Then substitute into the formula using point(4, 8)...and you can also use the other point if you wish to
; y - 8 = (-3)(x - 4)
; y - 8 = -3x + 12
Hence the equation of the line....,
; y = -3x + 20
The answer is j+5-2
because sum means to add
