Question

What is the equation of the line in the graph? 4,0 0,4

Answer 1

find the slope soooo its (y2-y1/x2-x1)= -4/4 so -1 is slope
equation is y=-x+4

Answer 2

You have to find the slope using the slope formula:
`(y_2-y_1)/(x_2-x_1)`


`( x_(1) ,y_(1) ) = (4, 0)`


`( x_(2), y_(2)) = (0, 4)`


`(y_2-y_1)/(x_2-x_1) = (4-0)/(0-4) = (4)/(-4) = (1)/(-1)` = -1 = m

After finding slope, you have to find the equation using the point slope formula:


`(y - y_1) = m(x - x_1)`


`(y - 0) = -1(x - 4)`


`y = -x + 4`

Hence, the equation is y = -x + 4 .
