Choose the equation below that represents the line that passes through the point (7,2) and has a slope of -3

y = - 3 + 2x

Step-by-step explanation:

The equation of the line that passes through the point (7,2) with a slope of -3  is  y = -3x + 23

Solution:

We need to find the equation for a line that passes through the point (7,2) and has a slope of -3.

Let us use slope-intercept form to find equation of line

The equation of line in slope intercept form is given as:

y = mx + b  --- eqn 1

where "m" is the slope of line and "b" is the y-intercept

Here in this sum, given that slope "m" = -3

Given point is (x, y) = (7, 2)

Plug the given values in eqn 1 to find "b" :

2 = -3(7) + b

2 = -21 + b

b = 23

Now plug "b" and "m" values in eqn 1 to get the equation of line

y = -3x + 23

This is the required equation of line found using slope intercept form

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
