I hate math i dont understand it help please
2 answers:
parallel lines have the same slope
y = 4x-5 the slope is 4
slope intercept form
y= mx+b
the slope is 4 and the y intercept is 3
y = 4x +3
The slope intercept form is:
y = mx + b
"m" being the slope, "b" being the y-intercept (the y value when x = 0)
For lines to be parallel, the slope has to be the same.
The slope of the given equation is 4, so your parallel line's slope is also 4.
y = 4x + b
The y-intercept is at (0,3), so your y-intercept (y value when x = 0) is 3
y = 4x + 3

The first one is not proportional and the second one is proportional
Answer:
3.657 and 7.657 to the nearest thousandth.
Step-by-step explanation:
x - y = 4
x^2 + y^2 = 72
From equation 1
x = y + 4 so
(y + 4)^2 + y^2 = 72
y^2 + 8y + 16 + y^2 - 72 = 0
2y^2 + 8y - 56 = 0
y^2 + 4y - 28 = 0
y = 3.657.
so x = 7.657.
