P what equation in slope-intercept form represents the line that passes through the points (3,5) and (-9,2)
ivanzaharov [21]

Answer:

y =\frac{1}{5}x+\frac{22}{5}

Step-by-step explanation:

To write the equation of a line, use the slope formula to first find the slope.

m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{3--9}=\frac{3}{3+12}=\frac{3}{15}=\frac{1}{5}

Substitute m=1/5 and the point (3,5) into point slope formula.

y-y_1 = m(x-x_1)\\y-5=\frac{1}{5}(x-3)\\y-5=\frac{1}{5}x -\frac{3}{5}\\y =\frac{1}{5}x+\frac{22}{5}

The equation of a function is y = 10 – 9x.Find the value of x when
USPshnik [31]

Answer:

x = 2, x = 4

Step-by-step explanation:

The equation y = 10 - 9x is a linear equation and the value of either y or x can be found by substituting the given values of either y or x.

given that y = -8, and substituting this into equation y = 10 - 9x,

we have, -8 = 10 - 9x

10 + 8 = 9x

9x = 18; dividing both sides by 9

x = 2

given that y = -26, and substituting this into equation y = 10 - 9x,

we have, -26 = 10 - 9x

10 + 26 = 9x

9x = 36; dividing both sides by 9

x = 4
