Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 1/-7 = -0.142857142857143.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 1/1 = 1.
Slope is --7/1 = 7.
Equation in slope-intercept form: y=7*x+1.

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -4/3 = -1.33333333333333.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -4/1 = -4.
Slope is -3/1 = -3.
Equation in slope-intercept form: y=-3*x+-4.

This equation defines a horizontal line. There is no X intercept. Y intercept is

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 3.2/-2 = -1.6.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 3.2/1 = 3.2.
Slope is --2/1 = 2.
Equation in slope-intercept form: y=2*x+3.2.

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 0.75/-1 = -0.75.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 0.75/1 = 0.75.
Slope is --1/1 = 1.
Equation in slope-intercept form: y=1*x+0.75.

��both sides divide by

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 8/-3 = -2.66666666666667.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 8/1 = 8.
Slope is --3/1 = 3.
Equation in slope-intercept form: y=3*x+8.
