Daniel needs 65 feet of oak boards and 100 feet of pine boards for a building project. each board will be cut into 5 ft lengths. which explanation correctly tells how to calculate how many more pine boards than oak boards daniel will have? a. step 1 multiply: 100 × 5. step 2 multiply: 65 × 5. step 3 subtract the two products. b. step 1 multiply: 100 × 5. step 2 multiply: 65 × 5. step 3 add the two products. c. step 1 divide: 100 ÷ 5. step 2 divide: 65 ÷ 5. step 3 subtract the two quotients. d. step 1 divide: 100 ÷ 5. step 2 divide: 65 ÷ 5. step 3 add the two quotients.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
