Answer:

Step-by-step explanation:
4x -10y= 40
Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.
10y= 4x -40
Divide both side by 10:

The product of the gradients of perpendicular lines is -1.
⅖(gradient of line)= -1
Gradient of perpendicular line



y = -2 and x= 3
Graph is attached below. Black line is the graph of y=-2
Blue line is the graph of x=3
Whenever we get equation like x = something, in that case slope is always undefined
Whenever we get equation like y = something, in that case slope is always 0
y = -2 and x= 3
For x=3, the slope is undefined.
The graph of x=3 is a vertical line at 3 on x. The x intercept is 3 and there is no y intercept.
For y=-2, the slope is 0
The graph of y=-2 is a horizontal line at -2 on y. The y intercept is -2 and there is no x intercept.
