Answer:
I think it is c too :))))))))
So this is using slope-intercept form (y=mx+b)
m is slope and b is the y-intercept
Looking at the graph, the line goes through the y-axis at (0,-5) so -5 is your y-intercept.
The slope of the line can be determine by using "rise over run". Find two points on the graph (I used 0,-5 and 1, -2). Count up from -5 to -2 (you get 3), count over from 0 to 1 (you get 1). Rise over run means that the slope equals 3.
Now, you just have to plug the numbers in.
Slope = 3; y-intercept = -5
y = 3x -5
The answer is A.) Y= 3x - 5
Hope this helps. Lmk if you need any more help :)
Answer:
20
Step-by-step explanation:
Since both triangles are similar, then the ratio is 18:6, which is 3:1
Triangle ABC is 3 times the size of DEC.
So, 1/3 of 30 is 10, and 30-10 is 20.
B 50 x 70
Since 52 rounds to 50 and 67 round to 70
Heya! Princess Kimmie
Let the Direct Variation Equation of Given Ordered pairs be : y = nx
Given : y = 4.8 when x = 4
Substituting the above values in our Equation, we get :
⇒ 4.8 = n × 4
⇒ 
⇒ The Equation is y = 1.2x
Option 3 is the Answer
