Make x the subject of this equation: ax+2=3x+b Please!! Thank you

1 answer:

4 0

Simply just isolate x to the left on its own first.
ax+2=3x+b
-2 -2
ax=3x+b-2
-3x -3x
ax-3x=b-2

Then factorise x out
x(a-3)=b-2

Ans: x = $\frac{b-2}{a-3}$

Find the point-slope equation for the line that passes through the points (-8,-32) and (3,1). Use the first point in your equati

emmainna [20.7K]

Hey there! :)

Answer:

y + 32 = 3(x + 8)

Step-by-step explanation:

Begin by finding the slope of the line using the slope formula:

$m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$

Plug in the coordinates of the points into the equation:

$m = \frac{1 - (-32)}{3 - (-8)}$

Simplify:

$m = \frac{33}{11}$

m = 3.

Point-slope form is:

y-y₁=m(x-x₁)

Plug in the coordinates of the first point, as well as the slope:

y - (-32) = 3(x - (-8)

y + 32 = 3(x + 8)
