Answer:
19/16
Give Step-by-step explanation:
I will help you with numbers 1 hopefully that will make the rest easy. so to start off you can find the y-intercept of the points (0, 5) and (8, 2) by use your equation
the 1 and 2s being the first and second values of you points so it would be 2-5/8-0 wich would = -3/8 than you plug that into your slope intercept equation y=mx +b so you would get y=mx -3/8 than you just pick a point I went with (8,2) just plug in x for x and y for y so ypu would get 2=2m-3/8 now you just solve for m or you slope. start by getting 2m on one side by adding 3/8 to both sides than getting 2+3/8=2m than combined your fraction by getting like Denominators in this case cange the 2 to 2/1 and multiply by 8 and then you just add across so you would get 16/8+3/8=2m 19/8=2m now you just devied by 2 on both sides to get m getting m=19/8/2 inorder to reduce the fraction you do keep change flip by keeping 19/8 the same and flipping 2/1 getting 19/8 times 1/2 than you just cross multiply and get you slope 19/16
