Hi, I have explained this below:
Q: y= +2x-3
Y Int = -3
Gradient = -2
or -2/1
Remember Rise over Run
Now as the gradient is a negative number, go down 2 run 1
Good Luck!

y = 2x + 3
y must have a value of 0 at the x-intercept.
That depends on the value of the y intercept but in general it is at (0, y intercept)
The y-intercept on the graph shows where the graph crosses the y-axis. The value is always the value of y at that point, because x is always equal to zero.
3y = -5x+2 y = -5/3x+2/3 The gradient is -5/3 and the y intercept is 2/3
