Answer: -3y +4
Step-by-step explanation:
64:4 = x:30
30/4 = 7.5
64 x 7.5 = 480 letters in 30 seconds
y = mx + b
m = -3/4
y = (-3/4)x + b
Use the given point (4,-6) to find b:
-6 = (-3/4)(4) + b
-6 = -3 + b
b = -3
Final equation:
y = (-3/4)x - 3
Answer:
y=0.5x-2
Step-by-step explanation:
if it is perpendicular to the line y=-2x-6, then you know that its slope is the negative reciprocal of that line, and it has a different y intercept which you need to solve for using the point given. You solve by plugging in the x and y values from the point and plugging in the slope into the standard equation, and solving for b, the y intercept
y=0.5x+b
1=0.5(6)+b
1=3+b
-2=b
