Answer:
C. The y-intercept of the graph is 4 so it is the smallest.
Step-by-step explanation:
A would not be correct since it has a y-intercept of 10.
B. would not be correct since it has a y-intercept of 6.
D. would not be correct since it has a y intercept of 6.
Slope = (-5-1)/(7+1) = -6/8 = -3/4
Perpendicular slope = 4/3
Midpoint = ((-1+7)/2 , (1+(-5))/2) = (3, 3)
equation:
y = mx + c
y = 4/3 x + c
at point (3, 3)
3 = 4/3(3) + c
c = 3 - 4 = -1
y = 4/3 x - 1 or 3y = 4x - 3
Answer:
10 hours
Step-by-step explanation:
More time will be required to cover a greater distance given that the speed is constant.
Speed required to drive 520 miles will be ,
= 10 hours
Let's write that as an equation.
x-8=4x+7
So, you must solve for x by putting all of x on one side then solving for the value of one x.
x-8=4x+7
-8=3x+7
-15=3x
-5=x
Check your work.
(-5)-8=4(-5)+7
-13=-13
number 3 is your answer x<-y+4/2-4
