Finding Slope of a Line
Graph the following equation:
y = 4x + 3
begin at 3 on the y-axis, go up 4, right 1
When dividing with exponents, what is the rule?
keep the base and subtract the exponents
Write the expression in standard form.
3.45 x 105
345,000
What form of equations do we use for lines?
y = mx + b or slope intercept form.
Identify the slope: y = -5x + 3
slope is -5
When graphing linear equations, where do we begin?
We begin at the y-intercept.
When multiplying with exponents, what is the rule?
Keep the base and add the exponents.
Write the expression in standard form.
4.66 x 10-3
0.00466
Write an equation for a line with the following slope and points.
m = -4/5 b = -7
y = -4/5x-7
What is the y-intercept in this equation?
y= -3x - 6
-6
Graph the following equation. Include at least 3 points. y = 1/4x -5
Graph should start with the point at (0, -5) Movement should be 1 up and 4 to the right continuing to another point. Movement could also be 1 down and 4 to the left.
Restate this exponent in positive terms.

6.54 x 105
Write an equation for a line with the following slope and points.
m = 3/5 and (0, -6), (3, 0)
Hint- the y-intercept is found where 'x' is = to 0
y = 3/5x-6
Find the slope of the line that includes the following points. (6, -5) (-5, 7)
-12/11
Graph the following equation. Include at least three points. y = -4
Graph should begin with a point on the y-axis at -4. A horizontal line should be drawn through -4 extending on both sides of the y-axis.
Solve the expressioin.

Is 40,520 written correctly in scientific notation?
4.52 x 105
No- it should be 4.052 x 104
The amount y(in dollars) of money you have left after playing x games at a carnival is y = -0.50x + 6. How much money do you have after playing six games?
y = -0.50(6) + 10 y = -3 + 6 y = -$3
