Question

Write an equation of the line point(2,-1) and parallel passing through y=3x-5 write in slope-intercept form

Answer 1

y = 3x - 7

Explanation:

Since the lines are parallel, the slopes will be the same. In this case 3. Now we have to find the y-intercept. We will use the slope (3), the x (2) and y (-1) to help us do this. We get the x and the y from the ordered pair given(2,-1).

y = mx + b

-1 = 3(2) + b Plug in what you know

-1 = 6 + b Subtract 6 from both sides

-7 = b

Now we can write the equation

y = 3x -7
