Answer:
(0,1)(1,4)
Step-by-step explanation:
Put in any value of x to find y, then you have a coordinate, then plot it
lets say i pick 0 for x
y = 3(0) + 1
y = 1
(0,1)
lets say i also pick 1 for x
y = 3(1)+1
y = 4
You need atleast two points to plot a line, these are two points.
Since it starts at 50 and goes to 35....it is a decrease since the amount is going down, or getting smaller. To find the percent, first find the difference 50-35 = 15; then divide by the initial amount of 50. So, 15/50 = 0.3, and then convert that to a percent by multiplying by 100. Therefore the percent decrease is 30%
The slope m of a line
through points

and

is given by :<span>

Thus, the slope of the line passing through points </span><span>(−1, 7) and (2, 10) is
</span>

<span>
The equation of a line with slope m passing through a point P(a, b) is given by
(y-b)=m(x-a).
We can consider any of the points (-1, 7), or (2, 10). Let's choose (2, 10):
y-10=1(x-2)
y-10=x-2
y-x=-2+10
y-x=8
