Pls solve i will give brainliest ifcorrect

Line 1 is difficult to determine exactly. The graphed lines are thick compared to the grid lines, so it is impossible to see the intersections clearly.

1.)  k = -2/5    y = -2/5 x     OR  k= - 3/7

2.) k = -4/5   y = -4/3 x  

3.)  k= 2    y = 2x  

4.)  k = 1     y = x

Step-by-step explanation:

All of the lines intersect the origin, so the y-intercept is 0  that is the b  in slope intercept form.  

k, the constant in direct variation equations is the coefficient of x  That is m, or slope in slope intercept form.

You should be able to pick a y-value from any coordinate where the graphed line intersects the grid and divide it by the x value of that coordinate. For example, in line 1, the line crosses the grid at (-5, 2)  Divide 2/-5   BUT the line should intersect (5,-2) but that is not the case. Also  Line 1 does intersect (7, -3) so that is a possible point to calculate k.  -3/7  But line 1 does not intersect (-7,3) exactly. Going through this made the issue evident.

The procedure does work well for the other lines.

Sorry this can't be more definite. Contact the instructor to make the issue known!
