Answer: well i cant help... so dont be happy! :)
Point-slope form:
y - y₁ = m(x - x₁)
You need to find "m" which is the slope.
To do so, use the slope formula and plug in the two points:
m = -3
(x₁ , y₁) = (1, -5)
Plug this into the equation:
y - y₁ = m(x - x₁)
y - (-5) = -3(x - 1)
y + 5 = -3(x - 1)
Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept
In order to get the equation from point-slope form to slope-intercept form, isolate/get the "y" by itself.
y + 5 = -3(x - 1) First distribute/multiply -3 into (x - 1)
y + 5 = -3x + 3 Subtract 5 on both sides
y = -3x - 2
Answer:
60 minutes make an hour
Step-by-step explanation:
Because 1 hour = 60 minutes
If you divide each number, 6:9, by 3 you will get the simpliest form. My answer will have to be B. 2:3
