Question

the line passes through the points 0,8 and 4,13

Answer 1

for every 4 steps of x, y increases with 5.

Answer 2

\[\large y=ax+b\]

which letter tells you about the slope? a or b?

Answer 3

first find the slope by using the slope formula :
slope(m) = (y2 - y1) / (x2 - x1)
(0,8) x1 = 0 and y1 = 8
(4,13) x2 = 4 and y2 = 13

now sub that into your slope formula and find the slope

Answer 4

oh..he left...well....I tried

Answer 5

a lot of newcomers go offline within a minute, pretty sad, but nothing we can do about it.

Answer 6

they probable expect to get spoon-fed answers but that's not really a good way to educate yourself.
