Answer:
The initial value of the graph is 2. Third option is correct.
Step-by-step explanation:
It is given that A coordinate grid is shown with x and y axes labeled from 0 to 7 at increments of 1.
The line is passing through the points (0,2) and (7,5).
The point (0,2) is the y-intercept and graph labeled from 0 to 7, therefore 2 is the initial value.
Slope of line is
The equation of line is
Where, m is slope and b is y-intercept. So the equation of given line is
At initial condition the value of x is 0. So, put x=0.
Therefore the initial value of the graph is 2. Option 3 is correct.
Answer:
The first graph to the left
Step-by-step explanation:
The second graph is parallel lines so they will never intersect
The third graph one line so they are infinite solutions
The first graph will intersect at one point
Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.
Y = -4/3x + 5....the slope here is -4/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the original slope and change the sign. So we have -4/3....we flip it and it becomes - 3/4....we change the sign and it becomes 3/4. So the perpendicular line will have a slope of 3/4.
y = mx + b
slope(m) = 3/4
(5,-4)...x = 5 and y = -4
now we sub into the formula and find b, the y int
-4 = 3/4(5) + b
-4 = 15/4 + b
-4 - 15/4 = b
-16/4 - 15/4 = b
-31/4 = b
so ur perpendicular equation is : y = 3/4x + (-31/4) which is written as :
y = 3/4x - 13/4 <== ur answer
