Find the equation that represents a line with slope of 7 and y-intercept of -1?

Step-by-step explanation:

your equation is -1=7x+b so to put it in y= form, move the -1. your answer is y=7x+1

we have

slope [m]=7

y intercept [c]=-1

we have

equation of a line is

y=mx+ c

y=7x-1

7x-y=1 is a required equation.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
