Slope is -2/5 and y-intercept is 2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 10/5
y = -2/5 x + 2
- Step 2: Find the slope and y-intercept from the equation.
Slope, m = -2/5
y-intercept, b = 2

Answer:
75min or 1 hour 15min
Step-by-step explanation:
45/12 = 3.75min per problem
3.75 x 20 = 75min or 1 hour 15min
Answer:
-4 ≤ y ≤ 8
Step-by-step explanation:
The range is the set of y-values for which the function is defined. When we are asked to find the range of a function (given in a graphical form), we look from which y-value (lowest) till which y-value (highest) the function is graphed for (defined for).
First, looking at the y-axis, we see that 5 bars in the coordinates is 10 units, so each bar is :
10/5 = 2 units
Now, looking at the lowest value, we see that it is 2 units from y = 0, so that is at:
y = -2 * 2 = -4
Now, looking at the highest value, we see that it is 4 units from y = 0, so that is at:
y = 4 * 2 = 8
So, the range is from y = -4 to y = 8. This can be written as:
-4 ≤ y ≤ 8
