I have no clue what to do. I will give a problem, you can either show me how you answered it or show another example so I won't know the answer to #2. (1 was just naming the slope intercept form)
Find the slope and y-intercept of each:
2. y=2/3x+5 Slope: Y intercept:
Please help me.

@dr I want to know how to find that out, though.

The answer is literally right there in the function. m = slope b = y intercept

Slope is 5. I did this my freshman year. You're doing graphing right?
The formula is y = mx + b; b being the y intercept. In this case, b = 5, so it is the y intercept. |

| take the log on both sides, then use quadratic equation , then use factor theorm |

slope-intercept form: y = mx+b where m = slope and b = y-intercept so y=2/3x+5 m (slope) = 2/3 b = 5 |

slope is 2/3 because the coefficient to x is the slope.
the y-intercept is 5 because in the equation (i forgot its exact name, i took basic algebra long ago), y=mx+b. m is your slope and b is the y-intercept
so all you gotta do is look for the M and the B and there ya go |

| @pretty Wrong, just gtfo okay? This is freshman algebra/graphing which you probably have not done yet. B = Y intercept in the formula: Y=mx + b; b = 5; b = the y intercept; y intercept = 5 |

@fire
i said that?
im 17, i am PRETTY sure i have had basic algebra LOL |

y=mx+b y=2/3x+5
m is 2/3 (the slope)
b is 5 (the y intercept) |

"This is freshman algebra/graphing which you probably have not done yet. B = Y intercept in the formula: Y=mx + b; b = 5; b = the y intercept; y intercept = 5"
b does not equal y y = mx+b is slope intercept if you subtract mx from both sides you get b = y-mx (or b = -mx + y)
b = y-mx =/= b = y |

oh god nvm thought you said "B=Y" not "B = Y intercept" scratch that |

@fire
try reading what i said again.
i said the same exact thing as you. rather than trying to critique my math, how about you improve your reading comprehension skills
they're obviously under average. |

"m is the slope, sorry"
here is what is said, but taken out of context because you obviously lack the attention span to make it through a few sentences:
y=mx+b. m is your slope and b is the y-intercept |

I said everything was solved. There is absolutely no need for this talk.
