Question

Directions: From the graph, write the linear equation in slope-intercept form

Answer 1

From the graph, we can see the line is passing through the points (-3,0) and (0,-3).

So the x-intercept of the graph is -3 and y-intercept of the graph is -3.

The slope of the line passing through (-3,0) and (0,-3) is

`m=(-3-0)/(0-(-3))\Rightarrow m=(-3)/(3)\Rightarrow m=-1`

Hence slope of the line is m= - 1.

Now we know that equation of a straight line with slope m and intercept c is

`y=mx+c`

Hence the equation is

`y=-x-3`
