Question

plz help algebra fan and medal a couple of questions

Answer 1

6) Find the slope of the line. M= __________ 7) What is the slope of the line? M= _____________
Hint: slope is rise/run or (change in y)/(change in x)





8) What is the slope of a line passing through the pair of points (-5, -6) and (3, -1)? Hint: slope formula is (y_2-y_1)/(x_2-x_1 )


9) What is the slope of a line passing through the pair of points (3/2,-10) and (3, 7/2)? Hint: slope formula is (y_2-y_1)/(x_2-x_1 )



10) Write an equation in point-slope form for the line through the given point with the given slope.
(3,2):m=4 Hint: Point-slope form is y-y_1=m(〖x-x〗_1)


11) The table shows the height of a plant as it grows. Write an equation in point-slope form that represents the plant’s height at any time. Determine the height of the plant after 1 year.
Time Height
2 8
4 15
6 22
8 29

12) Write each equation in standard form. (Hint: Standard form has three requirements)
a) y=-4/7 x+2 b) y=-0.3x+0.8

13) Write an equation for the line that is parallel to the given line and passes through the given point. Write your equation in slope-intercept form.
y=5x-1;(-4,2)



14) Write the equation of a line that is perpendicular to the given line and that passes through the given point. Write your equation in point-slope form.
y-8=6/11 (x-5);(1,3)


15) Tell whether the lines for each pair of equations are parallel, perpendicular, or neither. Explain your response. (hint: both equations need to be in slope-intercept form)
y=-3x+4
3x+9y=10

16) Describe the y-intercepts of the two graphs below. The functions are y=|x| and y=|x|+2
17) Describe how the graphs of 18) Graph y=|x|-3 (Hint: make a table of values)
y=|x| and y=|x-4| are related.

Answer 2

is this a test or exam?

Answer 3

DO you have a graph cuz I can't find the slope without a graph or initial points.

Answer 4

sorry it is a study guide
