Question 35338: I don't know anything about geometry and I need to help my 4th grade son.
Please help on the following using a graph:
1. Draw four points on the graph of the equation y =3x + 1. Connect using a straight line.
2. Draw four points on the graph of the equation y =2x - 1. Connect using a straight line.
3. Draw four points on the graph of the equation y = x + 1. Connect using a straight line.
Draw four points on the graph of the equation y = 2x Connect using a straight line.

Thank you.

Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -1/3 = -0.333333333333333.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -1/-1 = 1.
  • Slope is -3/-1 = 3.
  • Equation in slope-intercept form: y=3*x+1.

You can find points by plugging numbers into the equation.

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 1/2 = 0.5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 1/-1 = -1.
  • Slope is -2/-1 = 2.
  • Equation in slope-intercept form: y=2*x+-1.

You can find points by plugging numbers into the equation.
