Answer:
Step-by-step explanation:
37) Take two point from the line.
(2 , 0) & (0,4)
Slope = (-2)
38) (7 , 0) & (3 , 2)
39) The line is parallel to x-axis and so its slope is 0
Slope = 0
40) The line is parallel to y-axis and so its slope is undefined
Slope = undefined

A math test
Step-by-step explanation:
I just Goggled it lol
Answer:
Line d y = -3x -3
Line e y = -3x -1
Line f y= -3x+2
To write the equation of a line, you need the slope and the y-intercept. The slope of each line is -3. Find the y-intercept on the graph and then substitute it into the equation y = mx+b for b.
Line d has y-intercept (0,-3)
y = -3x -3
Line e has y-intercept (0,-1)
y = -3x -1
Line f has y-intercept (0,2)
y= -3x+2
Answer:
(x,y)=(3/2, -1/2)
Step-by-step explanation:
2x+4y=1 /*3
3x-5y=7 /*(-2)
6x+12y=3
-6x+10y=-14
...........................
/ 22y=-11
y= -11/22
y= -1/2
2x+4*(-1/2)=1
2x-2=1
+2 +2
2x=3
x=3/2
so the solutionis (x,y)=(3/2, -1/2)
