Find an equation for a line that passes through the point (0, –3) and parallel to another line whose slope is 1.2.

Parallel lines have the same slope, therefore the line we are looking for has a slope of 1.2.

y=1,2x+b

Now, we can plug in the point to solve for the intercept.
-3=1.2(0)+b
-3=0+b
b= -3

Finally, we can fill in the equation with all the information we've uncovered.
y=1.2x - 3
