Question

17.

Match the information about each graph with the correct linear equation.

Information		Linear Equations
​(a​)	The graph of the equation has​ y-intercept ​(0,−99​).	A.	6 x plus y equals negative 96x+y=−9
​(b​)	The graph of the equation has​ (0, 0) as​ x-intercept and​ y-intercept.	B.	y equals 4 xy=4x
​(c​)	The graph of the equation does not have an​ x-intercept.	C.	y equals 7y=7
​(d​)	The graph of the equation has​ x-intercept ​(77​,0).	D.	x minus 7 equals 0

19.

Find an equation of the line having the given slope and containing the given point.

m=−2​,​(3​,5​)

20. Graph the equation using the slope and the​ y-intercept.

y=8/3x(in fraction)+2

23. find the area of the rectangle.  

A rectangle has a horizontal side of length "2 x4 and a vertical side of length

6 x3 cubed

28. Write the expression with only positive exponents. Assume all variables represent nondash-zeronumbers.

-a^-7

Answer 1

17)

a)The graph of the equation has​ y-intercept ​(0,−9​).

A)6x+y=−9

----

The graph of the equation has​ (0, 0) as​ x-intercept and​ y-intercept.

y=4x

-------------

The graph of the equation does not have an​ x-intercept.

y=7

-----------------

The graph of the equation has​ x-intercept (7,0)

x-7 =0

m=−2​,​(3​,5​)

y -5 = -2(x -3)

y -5 = -2x +6

y= -2x +6 +5

y= -2x +11

20)

y= (8/3)x +2

Plot the y-intercept (0, 2) and then obtain point moving 8 unit up and 3 unit right to reach at (3, 10)
