Question

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

Answer 1

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
