Graph the following equations; calculate the slope, xintercept, and yintercept, and label the intercepts on the graph.
Find an equation in slopeintercept form passing through the points (6.2,18.1) and (3.4,18.1).

Part 1. We don't draw graphs here. You have not provided any equations, anyway.
Part 2. Both points have the same y value. You therefore have a horizontal line with equation y = 18.1
The slope is zero and the yintercept is 18.2.

how would I do th equation on this problem?

drwls gave you the equation above.
"You therefore have a horizontal line with equation"
y = 18.1
points (6.2,18.1) and (3.4,18.1)
As drwls said above,
"The slope is zero and the yintercept is 18.1."
The slope intercept form of an equation is,
y = mx + b
m = 0
yintercept = 18.1
y = 0x + 18.1
y = 18.1 is the equation for the line.
