The slope intercept form of a line is y =mx +b. What variable represents the y-intercept? b ? The slope intercept form of a line is y = mx +b What variable represents the slope of the line? m ? You borrow $250 from your parents to that you can buy the iphone. You agree to pay your parents $25 a month to repay the loan. Which equation below illustrates the money you owe your parents, M, is a function of time in months, t. M= 25 - 250t M = 250 + 25t M=250 - 25t M=25+250t 16) The cost of renting a party room at the Pizza House is $65, plus $6 for each person who attends the party. Which number sentence could be used to find n, the number of people who attended a party that cost $245? D. 6n + 65 = 245 C. n + 65 = 245 6 A. 6n x 65 = 245 B. 6(n + 65) = 245 9) Paula is making 7 tablecloths. She needs 9.35 yards of fabric for each tablecloth. The fabric costs $4.50 per yard. Which equation can be used to find the cost of the fabric, c? A. C=9.35÷7x4.5 B. C=9.35+7x4.5 C. C=9.35x7÷4.5 D. C=9.35x7x4.5 1. 7) The graph of line, y = 2x + 3, is drawn on the coordinate grid below. Which table of ordered pais contains only points on the line? A. C.
B. D.
Which is an equation of the line with slope of -3 and a y-intercept of 5? y = -3(x + 5) y - 5 = 3x 3x + y = 5 y = 5x - 3 What is the slope-intercept form of the equation with a slope of 5 and a y-intercept of -8?
y=-8x+5 y=8x-5 5x - y = -8 y = 5x -8 y=-3/7x-2/7 y=-3/7x-1/8 y=3/7x-1/8 y=3/7x-2/7 Write the equation for the graph below in slope-intercept form. |
