Find an equation for the line with the given properties. Express the equation in​ slope-intercept form. Containing the points Upper (-4, -2) and (0, -9)a. 7x - 4y = 36
b. -7x - 4y = 36
c. 2x - 9y = -81
d. -2x + 9y = -81

Answer :

Answer:

7x-4y=36

Step-by-step explanation:

From the equation of a line

[tex]y=mx+c\\m=slope\\m=\frac{y-y{1}}{x-x_{1}}\\[/tex]

where m is the slope and c is the intercept.

first we determine the slope from the given points (-4,-2) and (0,-9)

[tex]m=\frac{-2+9}{4-0}\\ m=7/4\\[/tex]

hence we can write our equation as

[tex]y=\frac{7}{4}x+c[/tex]

next we determine the value of the intercept

using the equation

[tex]y-y_{1}=m(x-x_{1})\\at point (0,-9)\\y-(-9)=m(x-0)\\y+9=\frac{7}{4}x\\4y+36=7x\\7x-4y=36[/tex]

hence option A is correct
