Write the slope-intercept (y = mx + b) form of the equation from the information given.

The line goes through the points (-1, -7) and (-8, -2)
Can someone please help me?

this is the same kind of question that was answered here, just change the numbers

I know but I couldn't figure out the equation

((-2-(-7))/((-8-(-1)) to find m

then plug in m and use one of the coordinates and plug that into y=mx+b

To find the slope-intercept form of the equation, y = mx + b, we need to determine the values of m (slope) and b (y-intercept).

First, let's find the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)

Given points: (-1, -7) and (-8, -2)
Plugging these values into the formula, we have:
m = (-2 - (-7)) / (-8 - (-1))
m = (-2 + 7) / (-8 + 1)
m = 5 / -7

Now that we have the slope, we can substitute one of the given points and the slope into the equation y = mx + b to find the value of b.

Using the point (-1, -7):
-7 = (5 / -7) * (-1) + b
-7 = -5/7 + b

To solve for b, let's add 5/7 to both sides of the equation:
-7 + 5/7 = b
-49/7 + 5/7 = b
-44/7 = b

So the y-intercept (b) is -44/7.

Now we have both m = 5/7 and b = -44/7, so we can write the equation in slope-intercept form:
y = (5/7)x - 44/7

Thus, the slope-intercept form of the equation is y = (5/7)x - 44/7.
