Answer:
Step-by-step explanation:
step 1
Find the equation of the first inequality
Find the equation of the first solid line
we have the ordered pairs
(0,-2) and (2,0)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
The equation in slope intercept form is equal to
we have
---> the y-intercept is given
substitute
Remember that
Everything to the left of the solid line is shaded
so
The inequality is
step 2
Find the equation of the second inequality
Find the equation of the second dashed line
we have the ordered pairs
(0,2) and (4,0)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
The equation in slope intercept form is equal to
we have
---> the y-intercept is given
substitute
Remember that
Everything below and to the left of the line is shaded
so
The inequality is
Rewrite
Multiply by 2 both sides
therefore
The system of inequalities is

35 2nd option
Step-by-step explanation:
The graph the line y = 4x -7 with slope 4 and y-intercept -7 is attached below.
The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Where x₁ - x coordinate y₁ - y coordinate
m - slope
Given the line with slope 4 and y-intercept -7
Now Write the equation as;
y = mx + c
y = 4x -7
Hence, the graph the line with slope 4 and y-intercept -7 is attached below.

Start on -7 since it is the y intercept(b). 4/1 is the slope. So from seven you would go up 4 right 1.
The sum of the numbers 487 and 310 is 797.
The process of increment of any number of quantities or the process of integrating small parts to make a big part is called summation.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation.
Given that the numbers are 487 and 310. The summation of the numbers will be calculated as:-
Summation = 310+487
Summation = 797
Therefore, the sum of the numbers 487 and 310 is 797.
