First, you have to take the equation and put into slope intercept form.
y=mx+b
B will be your y-intercept and m will be your slope. Slope is rise over run, so if it is negative, your line will be going down from left to right. If the slope is positive, the line will be going up from left to right.
Hope I could help :)
Solve it for 'y' .
You need to find the slope in the equation.
Points: (x1, y1) and (x2, y2) Slope: y1-y2/x1-x2
If you solve such an equation for "y", you get an equation in the slope-intercept form.

Here is how to solve it. First, find the slope of the given line. To do this, solve the equation for "y". That will convert the equation to the slope-intercept form. From there, you can immediately read off the slope. Since parallel lines have the same slope, the line you are looking for will have the same slope. Now you need to use the point-slope form of the equation, with the given point, and the slope you just calculated. Finally, solve this equation for "y" to bring it into the requested slope-intercept form.
To solve this, use the slope formula. the slope formula is m = (y2 - y1) / (x2 - x1) Therefore, m = ( -3 - 5)/ (1-2) If you solve this, you will get 8. So the slope of the line is 8.
Solve it for 'y' .
You take the change in Y or dy and divide it by the change in X or dx. Slope equals dy/dx.
8

Y = - 3X + 2 - 3 is the slope here ============== Whenever, you want to find the slope of a line, you first solve for the y = mx + b form of the function and then "m" is your slope.
Solve for y, getting the equation into the form of y = mx + b. m will then be the slope, and b will be the y intercept.
Solve the equation for ' y '.
