Given:
May painted 4 out of 8 equal parts of a poster board is blue.
Jared painted 2 out of 4 equal parts of the same sized poster board red.
May: 4/8 = 1/2 of the poster board.
Jared: 2/4 = 1/2 of the poster board.
The fractions are equal. Since the poster board is of the same size, both May and Jared painted equal parts which is 1/2 of the poster board.
The 8 and 4 only indicate the number of equal parts that are drawn on the poster board.
I can't see the rest of the graphs.
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
5/6 - x = 8/15
5/6 - 8/15 = x
25/30 - 16/30 = x
9/30 reduces to 3/10 = x <==Armand burned 3/10 of a row
