Answer:
Explanation:
A line can be defined by any two points on the line andhas the form
y=mx+b
Where m=slope and b=y intercept (value of y when x=0)
Slope is defined as
m=(y2-y1)/(x2-x1), we have points (0,7) and (1,4)
m=(4-7)/(1-0)
m=-3/1
m=-3 so the line is thus far
y=-3x+b, since we have the point (0,7) we know that b=7 so the line is
y=-3x+7
