Question

Determine the equation of the line given by the graph.
A)y = -2/7x+2/5
B)y = -2/7x+5/2
C)y = -7/2x+2/5
D)y = -7/2x+5/2

Answer 1

Answer:

y=mx+c y= -2/7+5/2 if this is right can i get brainliest and if u need explanation just ask

Answer 2

Answer:

D. y = -7/2x+5/2

Step-by-step explanation:

The formula for the graph would be: y = mx + c where m is the slope and c is the y-intercept.

Based on the graph, you can see that the y-intercept is 5/2 (somewhere between 5 and 0) so A and C are out. Remaining are options B and C.

Now, the slope is either -2/7 or -7/2. We will have to calculate the slope then. I will be using the points (-1, 6) and (1, -1)

$\frac{rise}{run}$ = $\frac{-1-6}{1-(-1)}$

    = $\frac{-7}{2}$

   = -$\frac{7}{2}$ (Same as option D)

Thus, the equation would have been: -$\frac{7}{2}$x + $\frac{5}{2}$
