Answer:
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: 
Step-by-step explanation:
The slope-intercept form of line is given by the formula:

Here m is the slope and b is the y intercept
Given

First of all, the slope has to be found

Putting m=1 in the equation

Putting the point (1,2) in the equation to find the value of b

The equation is:

Hence,
The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: 
Answer:c
Step-by-step explanation:
c
General formula to determine the equation of the liney - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope
Find the slopeGiven:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)
We could find the slope by using this formula
m =

Plug in the numbers
m =

m =

m =

m = 7
The slope is 7
Determine the line equationPlug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
Max needs to run 15 laps around the track.
Step-by-step explanation:
Given,
Distance Max wants to run = 512 miles
Length around the track = 34 mile
34 miles = 1 lap
1 mile = 
512 miles = 
512 miles = 15.06 laps
Rounding off to nearest whole number;
512 miles = 15 laps
Max needs to run 15 laps around the track.

Well first move the x's over to get 9X+27=3y and -8x+40=8y. Now just divide to isolate the y . 3x+9= y and -X+5= y.
