So we want this in the form y = mx + b, the equation of a line.
First, since we have 2 points, we can calculate the slope:
m = (y₂ - y₁)/(x₂ - x<span>₁</span>)
m = (30 - 21)/(0-1)
m = -9
The slope is negative since the line is sloping downward.
To get the b value which is the y-intercept, we simply look at the graph and see where the line crosses the y axis. It crosses exactly at 30.
So the equation will be:
y = -9x + 30
You need -9 and 30.<span />
Answer:
car cost 19400
Step-by-step explanation:
y = 5000 + 300*m where m is the number of months.
m = 48
y = 5000 + 300*48
y = 5000 + 14400
y = 19400
The cost of the car is 19400
According to the graph, the slope value is 3/1 with the rise over run test, the y-intercept is (0,4) and the slope is positive. All this proves that the function would be y = 3x + 4.
Answer:
D. 4(11y + 22)
Step-by-step explanation:
4 times 11 is not 45 so D is the answer
