Question

How do you find the intercepts for `y=8x-3`?

Answer 1

`x = 3/8 , y = -3`

Explanation:

This is the equation of a line. When the line crosses the x - axis , the y-coordinate will be zero. Substitute y = 0 into the equation to find x-intercept.

hence: 8x - 3 = 0 → 8x = 3 → x `= 3/8`

Similarly, when the line crosses the y-axis , x-coord will be zero.

hence: y = 8(0) - 3 = 0 - 3 = -3
