Slope = 1
y-intercept = -3, which can be expressed as (0,-3).
y - y_1 = m(x - x_1)
y -(-3) = 1(x - 0)
y + 3 = x
The slope-intercept form is
y = x - 3.
The standard form is Ax + By = C.
y = x - 3
3 = x - y
Done.
Answer:
Add the equations in order to solve the first variable. Plug this value into the other equation in order to solve the remaining variables.
The point form is (3,-1)
The equation form is x = 3, y = -1
Hope this helps!
<u><em>PLEASE, </em></u>consideer brainliest. I only have 3 left and then my rank will go up.
SA=(a+b+c) h+bh
=(5+12+13)*4+5*12
=20*4+60
=80+60
=140 cm squared
-7x + 6 = 27
-7x = 21 (Subtract 6 from both sides)
x = -3 (Divide -7 from both sides)
