Slope intercept form: y = mx + b
m = slope
b = y-intercept.
We have m which is -2
y = -2x + b
We need to find the y-intercept so plug 6 for x and 7 for y (6,7)
7 = -2 * 6 + b
7 = -12 + b
19 = b
Now put b in the equation
y = -2x + 19
m = slope
b = y-intercept.
We have m which is -2

We need to find the y-intercept so plug 6 for x and 7 for y (6,7)

Now put b in the equation
y = -2x + 19
The slope-intercept form is expressed as y = mx + b where m is the slope of the line and b is the y-intercept. To be able to write the given information, into this form, we use the point slope form. We do as follows:
y − y1 = m(x − x1)
y − 7 = -2(x − 6)
y - 7 = -2x + 6
y = -2x +13
y − y1 = m(x − x1)
y − 7 = -2(x − 6)
y - 7 = -2x + 6
y = -2x +13
