First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6
a common what? denominator?
Answer:
1.x = 80/8= 10
Step-by-step explanation:
2. (D)
3. (B) Hope it helps
D. -2, if the lines are parallel then the slope is the same but the y-int is different
