Can someone please check my work?

Write the slope-intercept (y = mx +b) form of the equation from the information given.

1. Slope = ½ and b = -3

Y=1/2-3

2. Slope equals 2 and the line goes through the point (-1, 3)

Y=2x+5

3. The line goes through the points (8,5) and (9, 6)

Y=x-3

4. The line goes through the points (-1, -7) and (-8, -2)

Y=-5/7x+(-54/7)

5. The line goes through the points (1/2, 3/2) and (-1/4, 5/4)

Y=1/3x+4/3

good job, all correct except a technically in the first.
You forgot the x in (1/2)x

1. Slope = ½ and b = -3

Y=1/2-3 ---------> y =(1/2)x - 3
Oh ok thank you soo much!!
Write the equation of each line using the given information.

both lie on the line.
m
=
