a.
Solution Given:
Slope of the line passing through the point is
m= ![\frac{y_2-y_1}{x_2-x_1}=\frac{3-(-5)}{-2-2}=\frac{8}{-4}=-2](https://tex.z-dn.net/?f=%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B3-%28-5%29%7D%7B-2-2%7D%3D%5Cfrac%7B8%7D%7B-4%7D%3D-2)
<u>slope=-2</u>
b.
Solution given:
equation is
2x-5y=-10
2x+10=5y
y=2x/5 +10/5
y=2/5 x +3
comparing above equation with y=mx+c
we get
m=2/5
<u>slope=2/5</u>
c.
Slope of the line passing through the point is
m=![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
-4=![\frac{1-(-9)}{0-x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1-%28-9%29%7D%7B0-x%7D)
-4=10/-x
doing criss cross multiplication
-4*-x=10
4x=10
x=10/4
x=5/2
<u>slope=5/2</u>
d.
we have
equation of line passing through the one point is
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=%20y-y_1%3Dm%28x-x_1%29)
y-5=-7(x-(-1))
y=-7(x+1)+5
y=-7x-7+5
<u>y=-7x-2 is a required equation:</u>
Answer:
-175
Step-by-step explanation:
230 = 55-y
230 - 55=-y
175= - y
y= -175
Just move the numbers to one side and variables to the other
