Can someone help with this math question

Answer 1

We can find the y-intercept by writing the slope-intercept form of the equation. For that first we need to find the slope of the given line.

$Slope=m= \frac{17-3}{10-6}= \frac{7}{2}$

Using the slope m =7/2 and a point (6,3) we can write the equation of the line as:

$y-3= \frac{7}{2}(x-6) \\ \\ y= \frac{7x}{2}-21+3 \\ \\ y= \frac{7x}{2}-18$

The equation above is in the slope intercept form.Coefficient of x is the slope and constant term is the y-intercept.

So, the y-intercept for the line is -18. Therefore, option C is the correct answer
