Answer:
y = -4x + 8
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope Formula:
Step 1: Find slope <em>m</em>
<em /><em />
<em /><em />
m = -4
y = -4x + b
Step 2: Find y-intercept <em>b</em>
4 = -4(1) + b
4 = -4 + b
8 = b
Step 3: Rewrite linear equation
y = -4x + 8
Answer:
M' (5,-1)
D' (5,1)
A' (3,4)
W' (4,-1)
Step-by-step explanation:
We want to find the coordinates of Quadrilateral MDAW with vertices M(-1, 5), D(1,5), A(4,3), and W(-1,4) after a reflection across y = x.
We can find these coordinates by following the following rule:
Reflection over y = x rule : ( x , y ) ---> ( y , x )
Explanation of rule: Simply swap the places of the x and y values.
Applying rule to given coordinates:
M(-1,5) -----> swap x and y values -----> M'(5,-1)
D(1,5) ----> swap x and y values -----> D'(5,1)
A(4,3) -----> swap x and y values -----> A'(3,4)
W(-1,4) -----> swap x and y values -----> W'(4,-1)
So the coordinates of Quadrilateral MDAW after a reflection over the y = x line are M'(5,-1) , D'(5,1) , A'(3,4) , W'(4,-1)

Inequalities are used to represent unequal expressions
The solution to the inequality is:
The inequality is given as:
60>5(6-2x)
Rewrite the inequality properly as:
Divide both sides of the inequality by 5
Subtract 6 from both sides of the inequality
Divide both sides of the inequality by -2
Hence, the solution to the inequality is:
