Your friend has improved in his math class. on his first test he scored 50 points, and then he scored 53, 56, 59, and 62 points on his next 4 tests. his tests continued to improve following this pattern. if he took 15 tests, how many points did he score on the last test?

Step-by-step explanation: I think you skip count by 50s or something like that. So, it has to be 64.

the correct option is b

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
