Hi can you pls help :o

Question

Write the slope-intercept form of the equation of the line parallel to the graph of y = -2x + 5 that passes through (0, 1).

Answer 1

y = -2x + b

1 = -2(0) + b

1 = b

y = -2x + 1

Answer 2

Hi Abdul,

        y = mx + b  is slope-intercept form of the equation of a line.

      You need to find m which is slope and b which is y-intercept.

       Because the lines are parallel to each other they will have the same slope.

       Now we know that m= -2

       When solving for b, we need to find the y-intercept (a point where the graph touches the y-axis) and

that point is given to us in the problem @ (0,1).

Now we know that b = 1 (if you take the y value of the ordered pair).

Plug the values of m and b into the slope intercept form equation and you get:

                   y= -2x+1
