draw the line which will represent the graph of the equation y-2.5x=c if it's known it passes through the point K(2, -3)
Oksi-84 [34.3K]

The line will represent the graph of the equation y=2.5x-8.

The two points necessary to graph would be (2,-3) and (0,-8).

<h3>What is the slope-intercept form?</h3>

The slope-intercept form is y=mx+c

If the line passes through (2,-3),

let us plugin and find c.

So we get,

-3-2.5(2)=c

-3-5=c

c=-8

So, The equation of the line is y=2.5x-8.
