10y - 5x = 40 Add 5x to both sides
10y = 5x + 40 Divide both sides by 10
y = $\frac{1}{2}$ x + 4

The y-intercept is 4 and the slope of the line is $\frac{1}{2}$ .

You can find these by comparing your equation to the equation y = mx + b, where m is the slope of the line and b is the y-intercept.

Please help me with number six

Tpy6a [65]

$w = 2x = 2( \frac{y}{3}) \\ v = 2w = 2 \times 2( \frac{y}{3} ) \\ v + w + x + y = 180 \\ \frac{4}{3} y + \frac{2}{3} y + \frac{y}{3} + y = 180 \\ y( \frac{4}{3} + \frac{2}{3} + \frac{1}{3} + 1) = 180 \\ y = \frac{180}{()}$

If y=-5 when x=2,find y when x=8

LenaWriter [7]

You can’t really know the y value unless you’re told that they’re both directly proportional. if so, then check out the pic

Given: y = 3x - 4. what is the x-intercept? (0, -4) (0, 4/3) (4/3, 0)

ankoles [38]

X intercept is 4/3 because you plug zeros in for y to find the y intercept
