Question 66011This question is from textbook Beginning Algebra
: Write the equation of the line with given slope and y-intercept. Then graph each line using the slope and y-intercept.
I am not quite sure what they mean by write out the equation of the line.
Slope: -2; y-intercept: (0, 4). I can do the graph but I do not quite understand what they mean by writing out the equation. Any help is appreciated. Thanks.This question is from textbook Beginning Algebra

Write the equation of the line with given slope and y-intercept. Then graph each line using the slope and y-intercept.
Slope: -2; y-intercept: (0, 4)
The slope-intercept form of a line is: highlight%28y=mx%2Bb%29, where m=slope and (0,b)=y-intercpet, your slope, m=-2 and your y-intercept, (0,b)=(0,4):
y=%28-2%29x%2B%284%29
highlight%28y=-2x%2B4%29
You said you know how to graph this, but just to be thorough:
Plot (0,4)
Form that point use your slope which is rise/run in this case -2/1 to plot another point. If you go down 2 and right 1 you should be plotting the point at (1,2)
Connect the two points and you should have a linbe that looks like this:
