Answer:
1.y−7=3(x+3)
2.y=3x+16
Step-by-step explanation:
use point-slope formula to find the slope and plug it into the equation
y-y₁=m(x-x₁)
slope= -
plug in the value of x and y from both of the coordinates into this equation and then use one set of points and slope to get your equation
Answer:
1/2
Step-by-step explanation:
u need to use those red dots
with the dot at the bottom you go 1 square to the right
and then you go 2 squares up
and ur answer is 1/2 and you might want to use rise over run = rise/run
Find slope of line A:
Move into slope-intercept form y = mx+b
<span>5x + 8y = -9
8y = -5x - 9
y = (-5/8)x - 9/8
The slope of line A is -5/8.
If </span><span>Line B is perpendicular to line A, then
slope Line B = negative reciprocal of slope Line A</span>
<span>slope Line B = 8/5
So like B has the equation
y = (8/5)x + b
If it passes through (10,10), we know that when x = 10, y = 10. Use those values to solve for b:
</span>
<span>y = (8/5)x + b
10 = (8/5)·10 + b</span>
<span>10 = (8)·2 + b
10 = 16 + b
b = -6
So line B has equation </span>
<span>y = (8/5)x - 6
m = 8/5 and b = -6
so
m + b = 8/5 - 6 = 8/5 - 30/5 = -22/5
So m+b = -22/5 or -4.4 in decimal form
