Write the equation of the line given the following info.

a. through: (1, 2), slope = 7

b. through (3, -1) slope = -1

c. through (-2, 5) slope = -4

d. through (3,5) slope = 5/3

Substitute slope for \'m\' in y = mx + b
y = mx + b

Step 2

Substitute the point (a,b) into equation
y = mx + b
2 = 7(x+b)

Step 3

Solve for b
b = -5

Step 4

Now that we know b, all that we have to do is put it into the equation and we now have our line in slope intercept

The equation of line passing through the point 1,2 and m= 7 is given by

a)y = 7x -5

m= 7

b = -5

b).y= 2-x

m = -1

b = 2

c).y=-4x -3

m = -4

b = -3

d)y = 5/3 x
