1) Write the equation in slope-intercept form that contains the following point with the given slope. Slope= 2 ; (-3, 1)





2) Tell me which lines are parallel to each other.
-6x + 2y = 8; y = 4; y = 3x; y = 3


3) Write the equation in slope-intercept form that contains the following point and is perpendicular to the given line
y = -4x + 3; (4, -2)





4) Write the equation in slope-intercept form that contains the following two points.
(4, -1) (-2, 8)






5) Given the equation y = 3x + 5 , write the equation of a new line that would have the same y-intercept but would be steeper.




6) A large company is expanding its workforce and needs to hire some new administrative assistants. They found the relationship between starting salary and months of experience. Their results are in the table. Find the equation for the line of best fit for this data using the calculator.


Please help!!!

Answer 1

1) y= 2x+ 5

2) -6x + 2y = 8; y = 3x;
because when u put the first equation in slope-intercept form the slope will be 3x. Notice parallel line are always the same slope.

3) perpendicular of -4x is 1/4x
y = 1/4x - 3

4. first u find the slope
slope is: -3/2
new find the slope-intercept form
by using the formula y-y1 = m (x - x1)
y = -3/2x + 5
