Explanation:

$\bold{\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(-1,\:-4\right),\:\left(x_2,\:y_2\right)=\left(1,\:2\right)}$

$\bold{m=\frac{2-\left(-4\right)}{1-\left(-1\right)}}$

3/4x - 5y = 7 X = -4y + 12 solve by substitution ! show work pls !!

tamaranim1 [39]

When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.

For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.

3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)

Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11
