y-intercept -3
slope 1/2
is sufficient info with which to write an equation for a straight line:
y = mx + b becomes y = (1/2)x - 3.
You should check this by determining whether or not (2,-1) satisfies this equation.
Answer:
C aka the third one
Step-by-step explanation:
Answer:
y = 1x+14
Step-by-step explanation:
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Substitute the point into the equation
10 = -4+b
Add 4 to each side
10+4 = -4+b+4
14 = b
y = x+14
2/21 is the answer
Hope this helps
So, parallel lines have the same slope, therefore a parallel line to 2x+12, will have the same slope as that one, so which is it?

so, we're really looking for the equation of a line whose slope is 2, and runs through -1,1.
