To easily find the slope and Y-intercept of a equation is always best to isolate the variable y from everything else. So from 8x+7y=53 I can subtract 8x from both sides. Now the equation is 7y=-8x+53, then you divide both sides by seven. So y=-8/7x+53/7 and simply the equation to a decimal form:
y=-1.14x+7.57 (rounded). Now the equation is in a slope-intercept form and you can easily find the slope and y-intercept.
slope: -8/7 or -1.14
y-intercept: 7.57 or 7 4/7

Finding the slop and y-intercept use the formula y=mx+b.
The m=slope and b= y-intercept
8x + 7y =53
-8x -8x
7y= -8x + 53
/7 /7 /7
y= -8x + 53
/7 /7
slope is m= negative 8 over 7
and y-intercept is 53 over 7

8x + 7y = 53
-8x -8x
7y = -8x + 53
/7 /7
y = 1 1/7x + 9
y intercept = 9
slope aka gradient of a line 1 1/7

8x + 7y = 53
-8x -8x
7y = -8x + 53
/ 7 /7 /7
y = -8/7 x + 53/7
The equation for a line is:
y = mx+ b
where m = slope
therefore for your equation
m = -8/7
