Question

How do you graph the line `y=2x-10`?

Answer 1

`"see explanation"`

Explanation:

`"one way is to find the intercepts, that is where the graph"`
`"crosses the x and y axes"`

`• " let x = 0, in the equation for y-intercept"`

`• " let y = 0, in the equation for x-intercept"`

`x=0rArry=0-10=-10larrcolor(red)"y-intercept"`

`y=0rArr2x-10=0rArrx=5larrcolor(red)"x-intercept"`

`"Plot the points "(0,-10)" and "(5,0)`

`"draw a straight line through them for graph"`
