Where does the graph cross the y axis at in y equals 5x-2?

Answer 1

y = 5x - 2

This follows the general equation for a straight line y = mx + c.

Where 'm' is the slope/gradient and 'c' is the y-intercept.

At the point the line crosses the y-axis , then x = 0

Hence

y = 5(0) - 2

y = -2 is the point the line intercept the y-axis.

Answer 2

point of crossing y axis is where x = 0

y = 5x -2

let x = 0

y = -2, point of crossing y axis
