Answer:
The Answer is: y = 2x - 3
Step-by-step explanation:
Given points: (3, 3) and (4, 5)
Find the slope, m:
m = y - y1/(x - x1)
m = 3 - 5/(3 - 4)
m = -2/-1 = 2
Use the Point Slope form of the equation:
y - y1 = m(x - x1)
y - 5 = 2(x - 4)
y - 5 = 2x - 8
y = 2x - 8 + 5
y = 2x - 3
Proof:
f(3) = 2(3) - 3
= 6 - 3 = 3, giving (3, 3)
-x+6>-(2x+4)
first distirubte
-x+6>-2x-4
add 1x to both sdies
6>-x-4
add 4 to both sdies
10>-x
multily -1 and don't forget to switch > to <
10<x
(9z+5)/4+18<26
multply both sdies by 4 to get rid of fraction
9z+5+72<104
add like terms
9z+77<104
subtract 77
9z<27
divide both sdies by 9
z<3
The slope of a line on a graph describes how "steep" the curve is by using the rise divided by the run (y=mx+b). The slope on the line graph usually represents how much of an increase or decrease is occurring per each unit
Answer:
-2
Step-by-step explanation:
Start with the vertex form of the equation of a parabola: y - k = a(x - h)^2
Here h = -2, k = -3, x = -1, y = -5. Find a:
-5 - [-3] = a(-1 - [-2])^2, or
-5 + 3 = a(1)^2, or
-2 = a
The unknown coefficient is -2.
