X/5 = 15 (solving linear equations)

I'm so close to finishing all these.

The coordinate grid shows points a through k. which points are solutions to the system of inequalities listed below? 2x+ ys 10 2x 4y < 8 oa c, d, k o e, f. g, j oa, c, d, h, k oe, f. g, h, j

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.
