What is the equation of the line in slope-intercept form?
y = 3x - 7
y = - 1 3 x + 7
y=-3x - 7
y =

y=mx + b (slope intercept form) m= slope, b =y-intercept

slope=rise/ run

Step-by-step explanation:

The slope intercept form is a line (straight line)

y = 3x - 7  slope 3 (rise=3, run = 1), y-intercept = -7

y = - 1 3 x + 7 slope -13 , y-intercept = 7

y=-3x - 7 slope -3, y-intercept = -7

in 4 days he will run   12/14

step-by-step explanation:

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
