Which graphed line represents an equation of a line with a slope -2 and a point on the line of(-1,2)?

y= -2x+0

Step-by-step explanation:

To graph this line you would first want to make an equation that is in slope-intercept form. To do this you will need the equation

(y-y1)=m(x-x1)

y1=you y value

m=slope

x1=your x value

(y-2)= -2(x--1)   Since it is x minus negative 1 you can change it to x+1

y-2= -2 (x+1) Now distribute the -2 to both terms inside the parenthesis

y-2= -2(x)-2(1)

y-2= -2x-2  Now add the two from the left to both sides.

 +2       +2    

y=-2x+0      Now you graph it. Your first point would be (0,0) since your y intercept is 0. From there you just go up two to the left one. Or Down two to the right one.
