Quiz 5.1 and 5.2 Alg 1 2/7/23

Determine the slope of the line through (-3, 8) and (-1, 8)

Answer explanation

y - y over x - x...if you got divide by 0 error...then you flipped this around.

Determine the slope of the line shown on the graph. Your answer should be a simplified fraction (not a decimal).

Answer explanation

rise over run. Negative slope.

Determine the slope of the line represented on the table. Your slope should be a simplified fraction (not a decimal).

Answer explanation

change in y over change in x

What is the y intercept of the graph? Your answer must be represented correctly...double check your notes for the correct way to write an intercept.

Answer explanation

If you just put the number 2, you were looking in the correct place, however, the intercept is a POINT!

Determine the y intercept of the line represented in the table. Make sure you give your answer as it is in our notes.

Answer explanation

To find the x intercept, you must find the point where y = 0. You have to add rows until you get there.

Determine the x intercept of the graph. Your answer must be written as it is in our notebook.

Answer explanation

Your answer had to be written as a POINT! Intercepts are points on the x and y axes!

Determine the x intercept of the line represented in the table. Make sure your answer matches the form it is written in our notes.

Answer explanation

For the x intercept, the y value must be 0. This value is given to you in the table. You had to express this answer as a POINT.
