Question

How do you graph `y=1/5x-4` by plotting points?

Answer 1

graph = graph{y=(1/5)*x-4 [-10, 10, -5, 5]}

Explanation:

Make a table of different values of `x` to find their `y`'s values

for example `x` = 0, substitute it in the equation to find the value of `y`

`y = 1/5 x - 4`

• `color(red)"x = 0" , color(blue) "y = -4"`

• `color(red)"x = 5", color(blue)"y = -3"`

• `color(red)"x = -5", color(blue)"y = -5"`

• `color(red)"x = 10", color(blue)"y = -2"`

• `color(red)"x = -10", color(blue)"y =-6"`

here I've chosen some values for `x` and try to choose values that will make your calculations in the equation easier and without fractions so you could graph it more accurate but of course, you can choose any value for `x`

`color(green)"then plot your points on the coordinate and match them!"`

graph{y=(1/5)*x-4 [-10, 10, -5, 5]}
