Question

How do you graph the equation y = 15x + 15?

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=15larrcolor(red)"y-intercept"`

`y=0rArr15x+15=0rArrx=-1larrcolor(red)"x-intercept"`

`"Plot the points "(0,15)" and "(-1,0)`

`"Draw a straight line through them for graph"`
graph{(y-15x-15)((x-0)^2+(y-15)^2-0.04)((x+1)^2+(y-0)^2-0.04)=0 [-40, 40, -20, 20]}
