Point slope form is the line through (a,b) with slope m is
y - b = m(x - a)
y - 8 = 5(x - 9)
y - 8 = 5x - 45
y = 5x - 37
Answer: y = 5x - 37
Answer:
B)
Step-by-step explanation:
(a-4)²-a-4
a²-8a+16-a-4
a²-9a+12
for example, let's look at the first set
y+3x =5 or y = -3x+ 5
and y = -3x + 2
y = m + b
the slopes are equal, the y-intercepts differ
that means, they're just parallel lines, no solution
9 times 5 equals 45 so yes
Answer:
y = 1/2 x + -5
Step-by-step explanation:
Slope-intercept form is y = mx + b
where m is the slope and b is the y-intercept
m is equal to change in y/ change in x ( aka horizontal change over vertical change), in the graph the horizontal change is 1 up for every 2 units right, which equals 1/2
b is the y-intercept (when x=0), if you look at the graph x=0 when y=-5
Lastly, you put in m and b into the equation to get y = 1/2 x + -5
