Question

The points (9,4) and (7,w) fall on a line with a slope of 5. What is the value of w?

Answer 1

-6

Explanation:

Equation .......

`\ slope\: = (different \: \: in \: y)/(different \: in \: x)`

So ,.

`\: \: \: \: \: \: \ \: \ \: \: \: \:5 = ((y1 - y2))/((x1 - x2))`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: 5 = ((4 - w))/((9 - 7))`

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 5 = (4 - w)/(2)`

5 × 2 = 4 - w

10 = 4 - w

W = 4 - 10

W = -6 ..........
