m=-1/2 through (2,4)
Y=mX+b
4=-1/2*2+b
4=-1+b
b=4+1
b=5
Y=-1/2X+5
SLOPE IS
(1-5)/(-2-1)=-4/-3=4/3
5=4/3*1+b
5=4/3+b
b=5-4/3
b=11/3

Write the equation of the line given:
a. m= -1/2 though (2,4)
One way to do this is to use the point slope formula: , where m=slope, (x1,y1)=given point.
m=-1/2 and (x1,y1)=(2,4)




slope intercept form of a line.
:
b. Through (1,5) & (-2,1)
You need to find the slope between the two points using the slope formula:
(x1,y1)=(1,5) and (x2,y2)=(-2,1)



Now that you have a slope and a point you can find the equation of the line using the point slope formula. m=4/3, (x1,y1)=(1,5)









Standard form of a line.
Happy Calculating!!!
