Question

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

Answer 1

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

Answer 2

Oh ok thank you soo much!!

Answer 3

Write the equation of each line using the given information.

The points
(
2
,
1
.
5
)
2
,
1
.
5
and
(
−
5
,
36
.
5
)
-
5
,
36
.
5
both lie on the line.
m
=
4
m
=
4
and the point
(
3
,
15
)
3
,
15
lies on the line.
It has the same slope as
y
=
1
y
=
1
and passes through
(
3
,
−
8
)
3
,
-
8
.
m
=
2
m
=
2
and it has a y-intercept of
(
0
,
4
)
0
,
4
.
