Find the equation of the line.​
JulsSmile [24]
Answer: y = 2x + 5

Explanation:

The slope (number before x) is rise (change in y)/run (change in x). The rise is 6 and the run is 3, so the slope is 6/3, or 2.

The second blank is the y-intercept, or where the line crosses the vertical axis. This point is at 5.

Hope this helps!

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)


For lines to be parallel, they have to have the SAME slope.


For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)

For example:

slope is 2

perpendicular line's slope is -1/2

slope is -2/3

perpendicular line's slope is 3/2



9.) First find the slope of line PQ. Use the slope formula and plug in the two points.

P = (4, 1)    (x₁ , y₁)

Q = (8, 4)       (x₂ , y₂)

m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{4-1}{8-4}

m=\frac{3}{4}


Line RS is parallel to line PQ, so they have the same slope of 3/4


y=\frac{3}{4}x+b

To find "b", plug in the point R = (3, -2) into the equation

y=\frac{3}{4}x+b

-2=\frac{3}{4}(3)+b

-2=\frac{9}{4}+b      Subtract 9/4 on both sides

-2-\frac{9}{4}=b     Make the denominators the same

-\frac{8}{4} -\frac{9}{4}=b

-\frac{17}{4}=b


y = \frac{3}{4}x- \frac{17}{4}



10.) Find the slope of line PQ

m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{4-1}{8-4} =\frac{3}{4}


Line RS is perpendicular to line PQ, so the slope of line RS is -4/3

y = -4/3x + b

Plug in the point R = (3, -2) into the equation to find "b"

y = -4/3x + b

-2 = -4/3(3) + b

-2 = -4 + b    Add 4 on both sides

2 = b


y = -\frac{4}{3}x+2
