# Module 2 - Graphing

Question | Answer |
---|---|

Graph y=1/2x+4 | Locate the y-intercept (4,0) on the graph and plot the point. From this point, use the slope (1/2=up positive one over positive two) to find a second point and plot it. Draw the line that connects the two points. |

write the equation Slope=1/4 y-intercept=-3 | y=mx+b m=1/4 and b=(-3,0) y=1/4x-3 |

Graph y=-3x+2 | Locate the y-intercept (2,0) on the graph and plot the point. From this point, use the slope (-3/1)=down negative three over positive one) to find a second point and plot it. Draw the line that connects the two points. |

Rewrite y=2x-6 in standard form | y=2x-6 -2x+y=2x-2x-6 (subtract 2x from both sides) -2x+y=-6 -1[-2x+y=-6] (multiply all items by -1) 2x-y=6 (the equation is now in standard form) |

Slope -6; y-intercept (0,2) | The equation is f(x)=-6x+2 |

Slope 3; y-intercept (0,-4) | the equation is f(x)= 3x-4 |

slope -2; y-intercept (0,7) | the equation is f(x)= -2x+7 |
