Step 1. I assume you want to plot this linear equation given in standard form.

Step 2. It takes two point to generate a line.

Step 3. Let x=0 then

Divide 4 to both sides of the equation

. So one point is (0,15/4).

Step 4. Let y=0, then

Divide 2 to both sides of the equation

. So another point is (15/2, 0).

Step 5. Use these two points (0,15/4) and (15/2,0) to plot the line.

Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 15/2 = 7.5.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 15/4 = 3.75.
Slope is -2/4 = -0.5.
Equation in slope-intercept form: y=-0.5*x+3.75.

I hope the above steps were helpful.
