Question

Function

Find the x -intercept/zero

Find the y-intercept

Find the slope

x = 0

Evaluate

4 x - 7 y \times 10 = 0

To find the x -intercept,set y =0

4 x - 7 \times 0 \times 10 = 0

Any expression multiplied by 0 equals 0

4 x - 0 = 0

Removing 0 doesn't change the value,so remove it from the expression

4 x = 0

Solution
