We can use substitution for the solution. Substitute y=2x-5 to -8x-4y=-20 so that you end up with -8x-8x+20=-20. Next you want to add like terms which will be -16x+20=-20, next you want isolate x by subtracting 20 from both sides and leaves you with -16x=-40. Divide -16 on both sides to fully isolate x and will leave you with x=2.5. Now substiture in 2.5 for x in y=2x-5 to get y=2(2.5)-5 which will then lead to y=0.

Please help me with the question

Damm [24]

Answer:

The right answer is Option 2:

$y+6 = -\frac{3}{4}(x-2)$

Step-by-step explanation:

Point-slope form of equation of a line is given by:

$y-y_1 = m(x-x_1)$

Here m is slope of the line and (x1,y1) is the point from which the line passes.

Given

Slope = m = -3/4

Point = (x1,y1) = (2,-6)

We simply have to put these value into the general form of equation of line in point-slope form

$y-(-6) = -\frac{3}{4}(x-2)\\y+6 = -\frac{3}{4}(x-2)$

Hence,

The right answer is Option 2:

$y+6 = -\frac{3}{4}(x-2)$
