4x+5y = 7
5y = -4x+7
y = -4/5x+7/5 in slope intercept form
So the slope of the perpendicular line is plus 5/4

Yes, I'm confident of that.
y=0.5x Gradient is 0.5 (half of 1) To explain how that equation works, every time y increases by 1, x increases by half. When drawn to the same scale for both x and y axis on the graph, it is 30 degrees upwards from the x-axis.
MATH 1003?
A parabola.
There is no y-intercept or slope for this given equation, because its graph is a vertical line perpendicular to the x-axis.
You plot the equation as a graph. Every one of the infinitely many points on the graph is a solution.
Any graph with the slope of -1/2

It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.

Gradient of given line is 2.1/5 = 21/50 So gradient (slope) of perpendicular is -50/21 = -2.381 (to 3 dp)
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
The coordinates of every point on the graph, and no other points, are solutions of the equation.
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
