Chemistry: What is the x-coordinate of the function below when the y-coordinate is 0? (0,5) (2,-5)

Hurricane season is coming back over here already and I’m going to be home by three and then I’ll come over later...

What is the x-coordinate of the function below

The equation of the function is assumed to be a straight line is of the form,

y= mx+c , where m,c

are the gradient and the y intercept respectively.

The gradient is computed using the formula for the gradient, i.e

$m=\frac{y_2-y_1}{x_2-x_1} = \frac{-5-5}{2-0} = -5$ .

The equation of the line is,

$y= -5x+c\\=5=-5(0)+c\\= c= 5$

The equation of the function is ,

y = -5x+5. .

The value of the x-coordinate when the y coordinate is 0 is found as shown below.

$0=-5x+5\\=x=1\\$ .

so the x-coordinate is 1.
