Hello!
We can find out our answer by plugging in the point (1,1) to see which equation works.
y=1.4(1.2)≠1
y=1.2≠1
y=0.5+0.3≠1
y=0.2+1.2≠1
As you can see, none of these answers are correct. You could make the last equation true by switching 0.2 to -0.2. It may have been a typo, so I would say the best answer is D.
I hope this helps!
Someone else asked the same question and got something written out for them. on another site, I found out that the first one was <span>: 8(14.13)=113.04</span>
Answer:
You didnt include the graph oop
Step-by-step explanation:
You can plot a linear equation, if you are given the coordinates and the slope for THE SAME line.
Assuming you have those, the first step is to find the y-intercept.
That is done by replacing
and
in the general formula by their coordinated counterparts, and replacing
by the slope that is given to you.
Let's assume the coordinates you are given are
, and the slope you are given is 1.
By substituting into the general formula...

...we can see that it is possible to find the y-intercept (
).
Knowing the y-intercept, it is possible to plot the line and solve any question.
I'll leave a picture of the example used above when graphed.
