Answer:
y=(3x/2)+3 and y=(-1x/2)-1
Step-by-step explanation:
So what I did was use rise/run to find the slope of the equation. Let's focus on the line going from the bottom left to the top right corner. For this line, I would start on (-2,0) which is one of the points plotted on your number line and count how much it is away from (0,3). You should get 3 units. After this, count how much it is to the right which is 2 units. Now, use rise/run to find the slope. 3/2, therefore the slope of the line is 3x/2. Now all we need is the y-int. For the Y int, all we have to do is see where the line touches the Y-axis which in this case is at (0,3). So your y-int would be 3. Now we can use this information to craft an equation in the form y=mx+b, m being the slope and b being the y int. We should get y=(3x/2)+3. Now repeat this with the other line to find the equation, but be careful!!! It has a negative slope.
Answer:
2 1/4 cups of sugar
Step-by-step explanation:
17.99 + 0.83m = 140
0.83m = 140 - 17.99
0.83m = 122.01
m = 122.01 / 0.83
m = 147 <== Mike drove 147 miles
Answer:
The equation of the line is y = 2x + 3
Step-by-step explanation:
In order to find this, we first need to find the slope. For that we use slope intercept form.
m(slope) = (y2 - y1)/(x2 - x1)
m = (15 - 7)/(6 -2)
m = 8/4
m =2
Now that we have this, we can use the slope and either point in slope-intercept form to get the equation.
y - y1 = m(x - x1)
y - 7 = 2(x - 2)
y - 7 = 2x - 4
y = 2x + 3
