Two less than the product of 5 and a number is 7.

5x-2=7

Step-by-step explanation:

We can format this expression because of the order of the words and specific phrases. Since it is two less than a product of 5 and a number, the number is undefined, so it must be a variable. Then the answer to the expression would be seven as stated by the problem.

correct answer:

b.(19,-2)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
