Question 56507This question is from textbook Beginning Algebra
: Can someone help me with this problem? I am lost!
I need to write the equation of the line with given slope and y-intercept. Then I need to graph each line using the slope and y-intercept.
Slope: -2; y-intercept: (0, 4)
Thanks,
Sher

Hi Sher,
The slope-intercept form of a line is:  , where m=slope and (0,b) is the y-intercept.
This time m=-2 and b=4, substitute them into your formula and you have:
To graph this, plot (0,4), from that point, use your slope to graph another point slope= , this time your slope is -, so go DOWN 2 units and right 1 unit and plot another point. You should be at (1,2). Connect the points and you should have a line that looks like:
Happy Calculating, Sher!!!
