Answer:
3/4
Step-by-step explanation:
We know this is a positive sloe because the line goes up from left to right.
We can pick to points (0,1) and (4,4)
We can find the slope from
m = (y2-y1)/(x2-x1)
= (4-1)/(4-0)
=3/4
Answer:
1.2%
Step-by-step explanation:
All you have to do is divide 12 by 10 and you get the answer 1.2.
Answer:
y = 3/4x + 10
Step-by-step explanation:
The equation of a line is y = slope * x + y-intercept
To find the slope, you choose two points and do (y1-y2)/(x1-x2): Point 1 can be (4,13) and point 2 can be (8,16) so, slope = (13-16)/(4-8) = -3/-4 = 3/4
The y-intercept is the value of y when x is 0, so it would be 10.
Put it together and you get y = 3/4x + 10
Answer:
y = -2x + 2
