Answer:
11x -8y = -9
Step-by-step explanation:
8x-4y=-4
-3x+4y=5
Subtract the second equation from the first
8x-4y=-4
-(-3x+4y=5)
-----------------------------
Distribute the minus sign
8x-4y=-4
+(3x-4y=-5)
-----------------------------
11x -8y = -9
The answer is option c- 68°
<h3>Of the four listed equations, B is the only equation that is not linear.</h3>
A linear equation is any equation that results in a straight line, as each value is a fixed number from the previous.
In a non-linear equation, a variable is being raised to a power, which results in a curved line.
The solution is in the picture
Answer:
y-4=-7(x-3) and y=-3/8x-8
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
the slope is already -7.
We can the just plug in the values: y-4=-7(x-3)
For the 2nd problem we can plug in values as well: -2=3/8(16)+b.
-2=6+b. the y intercept is -8. The final form is y=-3/8x-8
