Slope-Intercept Form
Slope = 4
y-intercept = -7
y=4x-7
Slope = -3
Point = (9,2)
y-2=-3(x-9)
give the structure of the piece wise function
________ ________
f(x)= ________ ________
________ ________
y-2=8(x-3)
y=8x-22
problem 7: is a linear model suitable for this situation?
yes because the prices are increasing linearly corresponding with the year
Slope = 1/8
y-intercept = 24
y=1/8x+24
Slope = 8
Point = (6,2)
y-2=8(x-6)
find the equation for the 2 flat lines
4,2
y+17=-3(x-1)
y=-3x-14
Problem 7: If Susan were to try to write the equation in the for of y=mx b what would b represent ? discuss with context.
B would represent how much the book costed in year 0ce
Line passes through; (1,12) and (0,9)
y=3x+9
(9,7) and (4,5)
y - 7 = 2/5 (x-9)
Find the equation of the sloped line
\frac{1}{3}x+2
y-11=1/5(x-5)
y=1/5x+10
problem 7 should you use point slope form or slope intercept form for this problem, after find the function for this problem
Your should use point slope form because as discussed in the previous problem b is not a reasonable number that we can find. The equation is y-1.2=0.05(x-2015)
Line passes through; (0,-7) and (8,-5)
y=1/4x-7
(-2,7) and (3,-5)
y-7=-12/5(x+2)
give constrain of the two lines
6<x
0\ge x
y+2=1/6(x-3)
y=1/6x-2.5
Solve for x.
5x+3=7x-1
2
(0,-2) and (3,4)
y=2x-2
(-2,6) and (4,7)
y - 6 = 1/6 (x+2)
give constrain of the sloped line
0<x\le6
y+3=-5(x+13)
y=-5x-68
Terra bought 5 boxes of noodles, 7 jars of sauces, and 2 bags of cheese. She paid a total of $45.50. If each box of noodles cost $2.34 and each jar of sauce cost $3.54. How much does one bag of cheese cost?
$4.51
