I think that first one represents a function.
Y=-2x-8+2
y=-2x-6
if x=0;Y=-6
IF y=0;x=-3
to plot the graph; plot point in -6 y-axis and -3 on the x-axis join them together then extend the line
hope u understood
Answer:
y=x
Step-by-step explanation:
y=mx+b
m is the slope
b is the y-intercept
Since the y-intercept is at the 0 axis, the y-intercept will be zero
So now the equation is looks like this:
y=mx (Since y=mx+0 doesn't make a difference)
Now find the slope
Which is 1
Thus y=x
Hope this helps!
Answer: 40
Step-by-step explanation:
You need to plug in 12 for x
5(12 - 4) = 5 x 8 = 40
Answer:
24
Step-by-step explanation:
Substituting...
4(3) - 6(- 2)
12 + 12
24
