Answer 1

The equation in slope-intercept form is

$y=mx+b$

Where

m is the slope

b is the y-intercept

The slope of an equation is the coefficient that multiplies "x", and the y-intercept of the equation is the number that is "alone" (i.e. is not related to any variable)

1) The equation must have "slope = 5", this means that the value multiplying "x" is five:

$y=5x+b$

The equation that includes this term is the first one

$y=5x-\frac{9}{5}$

2) The equation must have "y-intercept = -8/5", this means that the value that is alone is minus eight fifths:

$y=mx-\frac{8}{5}$

The equation that includes this term is the second one

$y=6x-\frac{8}{5}$

3) The equation must have "slope = -9/5", this means that the value multiplying "x" is minus nine fifths:

$y=-\frac{9}{5}x+b$

The equation that includes this term is the fourth one

$y=-\frac{9}{5}x+5$

4) The equation must have "y-intercept =6", the constant of the equation must be six:

$y=mx+6$

The equation that includes this term is the third one

$y=-\frac{8}{5}x+6$
