Answer:
C.y = 3x + 4
Step-by-step explanation:
We have two points, so we can find the slope
m = (y2-y1)/ (x2-x1)
= (7--2)/ (1--2)
= (7+2)/(1+2)
= 9/3
=3
The slope is 3
We can find the point slope form of the line
y-y1 = m(x-x1)
y-7 = 3(x-1)
Distribute
y-7 =3x-3
Add 7 to each side
y-7+7 = 3x-3+7
y = 3x+4
This is in slope intercept form (y=mx+b)
Answer:
This is a linear function so we must first find the rise than run of the table. -8 to -4 is a run of 4
-3 to 0 is a rise of 3
Next we divide rise/run so 3/4 and now we know that the slope is 3/4.
This is a linear function the school or website you got this question just did not give x=0 and y=3 to mess with you the students.
