16. Calculate the slope of the line that passes through the two points (-4,2) and (1,3). 17. Calculate the slope of the line that passes through the two points (-1,-2) and (2,7).
18. Identify the slope and y intercept of the following equation. 4y=x+8
19. Identify the slope and y intercept of the following equation. 3x+9y=56
If you can please show your work

Question 16

(-4 , 2) (1 , 3)

Insert values into formula

slope = 1/5 or 0.2

Question 17

(-1 , -2) (2 , 7)

Insert values into formula

slope = 3

Question 18

Divide each term in the equation by 4 to get it into the form where m=slope and c=y intercept

Now that the equation is in the form the slope and y intercept can be identified.

slope = 1/4

y intercept = 2

slope = 1/4 and y intercept = 2

Question 19

We have to rearrange the equation into the form where m=slope and c=y intercept

Divide each term in the equation by 9 to get it into the form where m=slope and c=y intercept

Now that the equation is in the form the slope and y intercept can be identified.

slope =

y intercept = 56/9

slope = and y intercept = 54/9

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
