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

If you are given the graph of a line in an xy-plane and its corresponding equation you can be sure that the coordinates of every point on that line will satisfy the equation?
Yes, I'm confident of that.
What is the slope of the line by the equation y equals .5x?
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.
Is a graph that consists of a single point the graph of a function and can you write the equation of such a function?
MATH 1003?
What is the shape of the graph of a quadratic equation called?
A parabola.
What is the y intercept and slope in this equation x equals -5?
There is no y-intercept or slope for this given equation, because its graph is a vertical line perpendicular to the x-axis.
How do you solve 21x-7y equals 4?
You plot the equation as a graph. Every one of the infinitely many points on the graph is a solution.
