Question

What’s the slope
(15,-14), (18,-10)
m =
Equation:
_b=

Answer 1

Slope: 4/3
Equation: y=4/3x-34

b=-34

Explanation:

To find the slope, we can use the formula m=(y_2-y_1)/(x_2-x_1)

Plugging in the values we get: m=(-10-(-14))/(18-15)

Simplifying we get: m=4/3

So the slope is 4/3

Now, to find the equation of the line in slope-intercept form (y=mx+b), you need to choose one of the points. Let's use (15, -14):

−14=

3

4

​

(15)+b

Multiply both sides by 3 to clear the fraction:

−42=4(15)+3b

−42=60+3b

Subtract 60 from both sides:

−102=3b

Divide by 3:

b=−34

So, the equation of the line is:

y=4/3x-34
