Parallel means it will have the same slope but a different y-intercept. So right now we have \[\large y=7x\] The next step is to plug in the "-4" for the x and see what you get for the y. :)
yes so right now this is how i have it
I am lost from here
Woah woah. We only have \(y=7x\) right now. We're solving from there. Can you plug -4 in for x?
Not the answer you are looking for? Search for more explanations.
No -2, take that out. It would be just \(y=-28\) But it should be \(y=-5\) since the set of points is (-4,-5). So what can you add to -28 to get -5?
Right. So the equation would be \[\large y=7x+23\] and that's it, we're done.
so can you PLEASE explain to me how i graph it?
Manually or on a calc?
manually on a line graph
Just plug in an x and then mark the cooresponding y. Once you've made enough dots at points, draw a line through them. I'll give you an example for x=1
\[\large y=7(1)+23\\\large y=30\] so the point would be (1,30)
