Question

Can someone please help me with this ​

Answer 1

y = -2x + 3

Explanation:

The slope of the line is (y2-y1)/(x2-x1)

= (7 --3) / (-2-3)

= 10/-5

= -2.

Using the point-slope form of a line and the point (3, -3):

y - (-3) = -2(x - 3)

y + 3 = -2x + 6

y = -2x + 3 is the required equation.

Answer 2

y=-2x+3

Explanation:

y=mx+b

m=
`(y_(2)-y_(1) )/(x_(2)-x_(1))`

m=
`(-3-7)/(3+2)`

m=-2

using (-2,7) we have

7=-2(-2)+b

b=7-4=3

so we have

y=-2x +3
